Girls has added a new boy.

Michael Zegan - most recently seen on Boardwalk Empire as Bugsy Siegl - has joined the Season 3 cast of this HBO hit, though details on his character are unknown at this time.

In light of Christopher Abbott suddenly departing the series as Charlie, however, it's safe to assume Zegan may become some kind of love interest for Alison Williams' Marnie.

The actor has also appeared on episodes of The Walking Dead, Rescue Me and How To Make It In America.

Girls, meanwhile, will return to HBO in early 2014.
