I never thought I’d say this, but I am really impressed with Lindsay Lohan. At least for her. If you were to hold Lindsay up to a regular person, probably not so much. But considering she’s nearly on par with Paris Hilton, she’s made some pretty big changes in her life – for the better. Lindsay’s relationship with DJ Samantha Ronson has really seemed to mellow her. She’s been acting much more mature lately, focusing on her work, not getting into any car accidents, and seemingly not drinking to such a ridiculous extent that she ends up in rehab. All big steps for her.

And it seems pretty clear that Sam is just as in to Lindsay. For her 22nd birthday last week, Ronson bought her a $22,000 diamond ring from Cartier. Not too shabby.

Samantha — the sister of super-producer Mark Ronson — reportedly splashed out the hefty amount on a Cartier diamond ring for Lindsay’s 22nd birthday.

Lindsay was later seen sporting the band when she and Samantha were shopping in LA. A source says, “Sam took Lindsay shopping to celebrate her 22nd birthday.

“Although Lindsay is the major breadwinner, Sam has her own money and is very proud.

“It’s not an engagement ring - simply a token of her commitment. Lindsay is thrilled and she and Sam are very content.”

According to a good deal of internet gossip, Sam not only pays her own way, she generally pays for Lindsay too. Considering the rumors of money problems that have been hounding LiLo for well over a year, that’s not too surprising.

Lohan made a cryptic comment about her birthday wish to Ryan Seacrest - and everyone is saying it’s as good as if she actually admitted that she and Sam are together.

“I just wanna live a happy, healthy year, continue on the path that I’ve been on and be with the person that I care about. And my family.”

Samantha also posted a picture of the two of them kissing on her MySpace page. I’m not sure what else the two of them can do to make it more obvious to us that they’re together. You know, except actually publicly acknowledging it.

Nicole Kidman is one lucky woman. Not only did she somehow manage to gestate without ever having a belly that indicated anything more severe than a little bloating, but she’ll probably come out of the whole thing with nary a stretch mark. And if her labor is as seemingly low-key as tiny as her pregnancy, she’ll pop the kid out in under half an hour. And for all that, she’ll get quite the “Thanks for having my baby” present from husband Keith Urban: a $73,000 Cartier ring.

With Nicole Kidman due to give birth in early July, Keith Urban has purchased a surprise present to give to his wife in the delivery room — a $73,000 Cartier Trinity ring! “It’s three rings intertwined, so it’s very symbolic,” the insider says of the popular design, which is set with multi-colored pavé diamonds and is meant to represent the three stages of a relationship: yellow gold for friendship, rose gold for love and white gold for fidelity.

“It’s three turned into one and that’s how it will be with Keith, Nicole and the new baby,” notes the insider. Cameron Diaz owns the same ring, as does Katie Holmes, who received hers for Mother’s Day. The Trinity ring was created by Cartier in 1924 and is still one of its most recognized designs today.

It’s a slightly odd choice given that Nicole’s ex-husband’s new wife has the same ring – but I’m sure she’s not complaining. It really is a lovely piece of jewelry. I made the mistake of looking at it on Cartier’s website – that can really get distracting. I would definitely be willing to have just about anyone’s child for that. Joking. Mostly.

Nicole is expected to give birth anytime. She hasn’t been specific about a date, other than that it’s in early July. Though if I were her, I’d put a rush on it. Jewelry is totally worth it.

Mariah Carey really is the epitome of tacky. After she and Nick Cannon fairly randomly flew off to the Bahamas to get married, everyone assumed they’d have some kind of local celebration when they got back here. There’s been a ton of gossip about it – but so far, nothing has materialized. That hasn’t stopped Mariah and Nick from registering for outlandishly expensive gifts. Which in and of itself is fairly tacky. But the absolute golden rule of wedding registries is that you don’t broadcast your gift list – you wait until you are asked where you’re registered. Of course that didn’t stop Mariah from having her assistant send out registry information to a hundred of her wealthy friends.

Mariah Carey’s friends and colleagues weren’t invited to her impromptu wedding to Nick Cannon, but they can still send a gift. According to an insider, “Mariah’s assistant, Gina, sent out over 100 e-mails to her wealthy friends letting them know that she’s registered at Bergdorf Goodman if they want to buy her a present. It’s odd because she’s not even having a big wedding party or anything. It was assumed they’d have a big celebration when they got back, but no. They just want the gifts.” On the list are “fine china, very expensive silver stemware” and other items. Carey’s rep declined to comment.

I wonder if Mariah could figure out a way to register for some class? I think if anyone would sell it, it’d be Bergdorf’s.

50 Cent and I clearly have a different definition of friendship. And I think I like his a hell of a lot more than mine. While I always thought it meant being there for the other person in good times and bad, occasionally drinking too much with them, complaining about men together, and having the occasional naked pillow fight, 50’s idea of friendship involves lavish vintage gifts. And I think that makes a hell of a lot more sense.

50 Cent knows how to treat his costars. Not content to drop off a basket of sugar-free muffins with a note saying “You were totally in the moment,” the rapper-thespian gave his Streets of Fire costar Val Kilmer a car, according to In Touch Weekly.

And not some tax-write-off clunker, either.

Fiddy bestowed on Kilmer a 1965 Chevy Impala said to be worth $100,000. The two, who play police officers dealing with the aftermath of Hurricane Katrina, bonded over their appreciation of classic vehicles, which led the rapper to give one of his very own autos to Kilmer.

Really? “Yes he did,” Fiddy’s rep told us. No word on Kilmer’s thank-you plans, but you can be sure of this: Muffins just ain’t gonna cut it.

[From E! News]

Sounds like the start of a bromance to me. And what a way to kick it off. At first I thought 50 might have some kind of non-sexual crush on Val Kilmer, a la that famous Seinfeld episode. But then I saw a picture of Val Kilmer, and… I have a policy of never making fun of someone’s weight. But let’s just say that if there were ever a time I would consider breaking that rule, it’d be right now. So I’m pretty sure there’s no crush going on here. But I think that explains E!’s joke about the sugar free muffins.

Either way, I think it’s very important that I star in a film with 50 Cent. I’d just like a Honda, thanks.
