At the same Help Haiti Home gala on Saturday where Sean Penn showcased his blossoming relationship with Charlize Theron, the actor's daughter also debuted a new romance.
Dylan Penn, 22, whose mom is Penn's ex, newly engaged actress Robin Wright, spent the evening cozying up to The Vampire Diaries star Steven McQueen, 25.
A source confirms to PEOPLE that the two are an item.
McQueen is Hollywood royalty in his own right: His grandfather and namesake is the late legendary leading man, best known for his iconic roles in films like 1968's Bullitt.
In September Penn was briefly linked with actor Robert Pattinson, but she later told GQ the rumors were "bulls---."
