Sean Penn has a new lady in his life and her name is Shannon Costello.
The couple took their romance public at the beginning of July and have been spotted together on the beach in Malibu, at Nobu earlier this month, and dining out in Miami.
Costello, initially misidentified by the media as Stacey Koplin, is the former communications director of the actor's J/P Haitian Relief Organization. She and Penn first met in fall 2009 and became friends. Costello began working with J/P in 2010.
Costello, 26, also worked on Davis Guggenheim's documentary Waiting for Superman and has worked at ABC News' 20/20. Along with Brian Grazer, she will be a producer for Ron Howard's film, Under The Banner of Heaven, which is in development.
