After-party trio! Following the 2014 Golden Globes on Sunday, Jan. 12, Kate Beckinsale attended an after-party with husband Len Wiseman and an unlikely third wheel: ex Michael Sheen.

The 40-year-old actress, looking gorgeous in a strapless Zuhair Murad gown, posed between Sheen and Wiseman on the red carpet at The Weinstein Company's party at the Beverly Hilton Hotel. Exes Beckinsale and Sheen, 44, were all smiles for photographers and shared a few laughs.

The red carpet run-in, however, may have been coincidental. An eyewitness tells Us Weekly that Beckinsale held hands with Wiseman while walking through the party, and Sheen brought up the rear. The threesome wore grim expressions, and parted ways shortly after. (Sheen did reportedly bring his and Beckinsale's 14-year-old daughter Lily as his date to the Golden Globes.)

Beckinsale and the Masters of Sex actor ended their relationship in 2003 after eight years. The Total Recall star married Wiseman in 2004.

"The popular notion of how Michael and I broke up —- that we were on [the first Underworld] and I ran off with the director [Wiseman] —- is just not true," Beckinsale told Entertainment Weekly in January 2012. "If that were the case, I think it would be very difficult and peculiar to have an okay situation. But everybody involved has felt that the priority is Lily and wanting to get to a good place for her. And everyone is nice. So it's not bad."
