Robin Wright closed out 2007 in the best possible way by bringing her marriage to serial douchebag Sean Penn to a long overdue close. The divorce papers blamed “irreconcilable differences” for the separation, and today some of the details of those differences began to emerge. Apparently Princess Buttercup didn’t see eye to eye with her spouse on the subject of drunken threesomes with Russian party girls.

Robin and Sean spent the holidays at Squaw Valley, and an anonymous source told the Star that things weren’t going well from the start:

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.

Presumably this was the straw that broke the camel’s back, since Sean has a well deserved reputation for behaving like an abrasive boor. Moreover, Robin stayed with him after he traveled to Caracas last August and swapped non-erotic backrubs with Hugo Chávez. Compared to that, getting down to it with a couple of drunken Russian girls sounds almost normal. But whatever the reasons, Robin is better off without the guy. Pity Madonna isn’t available to catch him on the rebound.
