Talk about a sexy trio.
The Masters of Sex star is Beckinsale's former longtime boyfriend and father of their daughter Lily.
The three posed arm-in-arm on the carpet at The Weinstein Company/Netflix party with the stunning Beckinsale in the middle. They were just as close inside the bash, too.

They were spotted at about 11 p.m. heading for the valet when Sheen said goodnight with a quick kiss on the lips with Beckinsale.
If only all former exes could get on so well.
Beckinsale and Sheen were together for eight years before calling it quits in 2003 after they filmed Underworld, which Wiseman directed.
Beckinsale and Wiseman married about a year later at the Hotel Bel-Air.
