Back when Jesse James and Kat Von D were just dating, circa fall of last year, there were often rumors about Kat spending time with other dudes. There were two rumors in particular that I found interesting – Kat with Nikki Sixx, and Kat with Bam Margera. She was spotted hanging out with both of them, and apparently both are former boyfriends too. Kat’s ex-husband, Oliver Peck, even went to the tabloids to talk about the Kat he knew – a superficial narcissist who screwed over friends and screwed around on him. So, basically, I wouldn’t be surprised if Kat cheated on Jesse James, despite the stories that Jesse was the cheater. I think both of them would and could easily have had affairs. This week’s Star Magazine claims that it was Kat, though – and that Jesse dumped her because she was boning Bam.

Star has learned that Jesse James broke off his engagement to Kat Von D after accusing her of cheating on him.

“Jesse believed Kat had been getting it on with her longtime friend Bam Margera, and they had a huge blowup over it,” an insider tells Star. “Given his past history with Sandra, Jesse’s over-the-top jealousy when it came to Kat is almost laughable.”

Trouble was percolating in Jesse and Kat’s relationship almost from the start.

“Jesse lives in Austin, and Kat’s based in LA, where most of her best friends are guys – many of whom she’s been intimate with in the past. There was always a lot of fuel to fire up Jesse’s Jealous nature.”

One of her closest friends is Bam, 31. A few weeks after Ryan Dunn’s death on June 20, “Bam went over to Kat’s LA home to hang out and talk, and he ended up spending the night. Jesse found out and questioned her about it, and Kat let slip something about how ‘Bam just can’t sleep alone.’ Jesse hit the roof when he heard that and accused Kat of cheating on him. They were barely hanging by a thread by then.”

The final nail in the coffin came after Jesse and Kat went to a Soundgarden concert on July 22: “After the show, Jesse wanted to go backstage and meet the band, but Kat refused A mutual friend told Jesse later that Kat had a romantic history with one of the band members – and she didn’t want to be around him with Jesse by her side” They broke up four days after the concert.

Kat was bonin’ errybody. Star’s insider also claims that Bam “has a long history with Kat. She needs constant companionship – and their friends believe he’s supplied it in the past.” Okay, y’all. No slut-shaming Kat. She did us all a great service by cheating on Jesse. Yes, she’s still kind of gross – not because she sleeps with everything with a pulse, but because she’s kind of smarmy and delusional and crazy. But she screwed Jesse over, so for that alone, she deserves a slow clap.

The toxicology results are in for Ryan Dunn, the Jackass castmember who died in a high speed car crash early Sunday morning. His passenger, a friend who was drinking with him at the bar until closing, was also killed. Dunn, 34, had a blood alcohol level of nearly .2, which is twice the legal limit in Pennsylvania where he died. Police estimate that he was driving from between 132-140 miles per hour in his Porsche 911 before he lost control.

Jackass star Ryan Dunn was drunk when he crashed his Porsche on a Pennsylvania highway while going as fast as 140 mph, according to police.

Dunn, 34, died along with his friend Zachary Hartwell, 30, from West Chester, Pa. Both men suffered “blunt and thermal trauma” in the crash, which turned Dunn’s car into a fireball, according to the autopsy report.

Dunn was driving at twice the legal limit, with authorities saying toxicology results put his blood alcohol concentration at 0.196 percent, while the legal state limit is 0.08.

Before the crash, the two men had been in a bar in West Chester; Dunn had Tweeted a photo of them drinking.

“The initial crash reconstruction investigation determined that Mr. Dunn’s vehicle was traveling between 132-140 mph at the time of the collision,” West Goshen Police Chief Michael Carroll said in a statement.

There’s local news video of Bam Margera at the crash site where his best friend Ryan died, and it’s really heartbreaking. He seems to have had a premonition that something happened to Ryan, because he explains that he was in Arizona and started freaking out around the same time that Ryan passed, punching out the windows and ripping out the stereo even though he didn’t know about the accident yet and had no reason to be angry about anything.

Bam’s mom told the local press that she was always warning Ryan to drive slower, and his friends said the same. In the audio commentary for season 5 of their reality show Viva La Bam, Bam, his mom April and his friend Tim talk about what a bad driver Ryan was and how he was always driving too fast and getting in accidents. (You can hear their discussion on this video.) They said back then that Ryan would probably die in a car accident, and sadly he did. I’m not going to get into whether it’s ok to use this as a teachable moment when it just happened and people are mourning. I feel like if this was my friend I would be angry and upset if people brought it up so soon, and if a friend of mine was killed by a drunk driver I would be angry and upset if it wasn’t brought up or was somehow glossed over because the person died. It’s just sad and such a waste.

Yesterday we heard that Ryan Dunn of Jackass passed away after he suffered a fatal accident in the Porsche 911 he was driving, killing himself and a 30 year-old Jackass production assistant Zachary Hartwell. He had tweeted a photo of himself drinking that night before the accident and he looked blitzed out of his mind. A source from the bar told TMZ that Ryan had had three beers and three shots in the four hours he was there before leaving at 2:10 am, closing time. That doesn’t sound excessive for a man of his size but we have no way of verifying that. As of yet the cause of the accident is unknown, although police say “speed” was a factor, and given the state of the wreckage we may never know. It’s entirely possible that he swerved to avoid something or that his tire blew out, but circumstantial evidence suggests he was drunk.

Movie critic Roger Ebert recently tweeted something that a lot of people have been saying about this guy’s death, that “friends don’t let Jackasses drive drunk.” It’s harsh, but many people have that sentiment about this accident. (TMZ live recently covered a lot of those comments. One person wrote that she was surprised that this is the first time one of the Jackass guys has died. They do incredibly dangerous stunts for a living, after all.) In response, Dunn’s friend Bam Margera went off on Ebert, which is understandable.

Is there ever a time to say to someone who is hurt, or to say about someone who died, that they should not have been drinking and driving? Yes, definitely. I don’t want to get too personal, but a friend of recently mine got in an accident while he was drinking and I called him on it. He was injured so I waited a little to bring it up. I was so angry that he made that stupid decision and I had to say something to him about it. I did it because I love him, but some may think I was being insensitive and he bitched that I was the only one who told him I was angry that he was drinking when it happened. Still, I get why Dunn’s friends are upset at Ebert’s comments. There’s a way to be tactful in situations like this where someone has died. Ebert was dismissive and seemed to suggest that someone could have prevented that guy’s death. Surely that’s what his friends are beating themselves up over right now.

Update: Ebert has issued a response to this controversy on his blog, explaining his position. It’s very well written and backed up by examples in the press that support what he was trying to say, simply that the kid should not have driven drunk. Ebert’s Facebook page has been removed by Facebook for a terms of service violation after it was flagged. That’s ridiculous and seems completely arbitrary and unfair.

Proving that there still are people stupid enough, or maybe realistic enough, to doom their showbiz relationships by appearing in MTV reality shows featuring such, Bam Margera and his new wife have let camera film the events leading up to their wedding for a series called Bam’s Unholy Union. The first episode aired on Friday and they were married this Saturday:

Bam Margera professional skateboarder, MTV star and amateur prankster, just earned himself another title: husband. Margera, 27, who became a punk hero on the shows “Jackass” and “Viva La Bam,” married childhood friend Missy Rothstein, 26, in downtown Philadelphia on Saturday.

The couple wed in front of about 350 friends and family members and an MTV crew.

Margera is making his path to marriage into a nine-part reality television series called “Bam’s Unholy Union.” The wedding itself will be shown in the final episode in early April.

The festivities included a performance by rocker Iggy Pop, as well as appearances by skateboard legend Tony Hawk and James Iha, formerly of the alternative rock band Smashing Pumpkins.

Known for his role on Jackass and a follow-up MTV reality series in which he tortures his family inventively, professional skateboarder Margera might not be swift or self-aware enough to wave off the cash for opening up his new marriage to the harsh light of reality TV.

Bam, 27, was engaged to Jenn Rivell, a 33-year-old single mom, until 2005, when their relationship ended amid accusations of his infidelity with Jessica Simpson on the set of The Dukes of Hazzard. Rivell called into a radio station with the story about Margera bragging in an e-mail that he bedded the then-married Simpson, which he denied, then admitted, then denied again.

Margera has known his new wife since they were in grade school together, and rumor has it that he cheated on Rivell with her, too. They are honeymooning in Dubai.
