Apparently Sean Penn decided to end his marriage with a bang. So to speak. According to MSNBC and various media outlets, Penn had a threesome with two drunk Russian girls. He had gone on vacation with wife Robin Wright Penn right before Christmas, but had booked separate suites for each of them. So clearly things weren’t exactly cozy before all of this. Robin Wright hardly saw Penn on vacation, and was pissed that she was spending all her time alone. When she went to Penn’s room, she found him in bed with two drunk women. Penn supposedly didn’t care, and continued to party into the night.

Sean Penn was served with divorce papers by his wife Robin after the actress allegedly found him in bed with two other women. Magazine Star has revealed details of the couple’s last weekend together and claimed the Mystic River star was caught being unfaithful to his partner of 11 years.

The actors were reportedly staying at the Squaw Valley resort in Lake Tahoe, California, days before Christmas when the incident is said to have occurred, according to MSNBC.com. A source tells the publication, “Sean didn’t spend much time with his wife – he booked her a separate suite – and when Robin got fed up with being alone, she went over to his suite. (There, she) found him drunk with two Russian girls.”

Penn married Wright in 1996 and they have two children together, Dylan Frances, 16, and Hopper Jack, 14. Wright filed divorce papers in California on December 21, citing irreconcilable differences as a reason for the split. The couple are said to be seeking joint custody of their teenage kids.

There’s always been something about Sean Penn that I’ve found distasteful. I thought it was the constant sneer plastered across his face, but now I think it probably has more to do with the sleazebag, ignoring your wife, having sex with strangers thing. Something tells me the two have a prenup, but if they don’t this could get pretty messy for him.

Update by Celebitchy: The Star article doesn’t say that Robin found Sean in bed with two Russian woman, just that she found him drunk and hanging out with them in his room. The article is being misquoted:

“Sean didn’t spend much time with his wife – he booked her a separate suite – and when Robin got fed up with being along, she went over to his suite and found him drunk with two Russian girls!” says a source. “He’d already finished a couple of bottles of champagne.”

Robin, 41, went nuclear, but Sean “just told her to leave and continued drinking,” reveals the source. Sean, 47, even flirted with the women in front of Robin, whom he married in 1996 after the birth of their children, daughter Dylan, 16, and son Hopper, 14. “He was acting like he just didn’t care,” says the source.

The article goes on to say that Penn tried to order champagne from room service at 3 am and then had someone drive him to a 7-Eleven when there wasn’t room service available at that time. He then found that he wasn’t able to buy booze after 2 am. That hardly sounds like someone who’s having a threesome. If you’re busy having sex you’re not about to get antsy over not getting booze.
