Sean Penn [1] hit the beach with a young woman in Hawaii last week who was later revealed to be Leila George, the 24-year-old daughter of actor Vincent D'Onofrio [2]. Sean was spotted taking a dip with the bikini-clad blonde and sharing a steamy kiss while swimming in the ocean. Also on hand for the sunset swim were Sean's 23-year-old son Hopper, whom he shares with ex-wife Robin Wright, and Australian actress Gracie Otto.

Sean's PDA-filled beach day marks the first time he's been seen getting romantic with a woman since his split from fiancée Charlize Theron [3] back in June 2015. On Thursday, People reported that Leila is an Australian native, born in 1992 to the former Law & Order: Criminal Intent star and his then-girlfriend, Greta Scacchi. While Sean was rumored to be hooking up with Minka Kelly [4] back in April, the reports were never confirmed, and he and Charlize kept things friendly and civil [5] while promoting their movie The Last Face at the Cannes Film Festival in May.
