Sean Penn has a new leading lady in his life and her name is Shannon Costello. The new couple took their romance public at the beginning of July, when they were spotted on the beach. Earlier this month they were spotted having dinner at Nobu. Shannon was initially misidentified as Stacey Koplin.

Shannon and Sean met in the fall of 2009 and became friends. 26-year old Shannon used to be the communications directer of Sean's J/P Haitian Relief Organization, she also worked on Davis Guggenheim's documentary Waiting for Superman and worked for ABC News's 20/20. She has just started a new project: producer, along with Brian Grazer, for Ron Howard's film Under The Banner of Heaven.
