Sean Penn is all smiles

Sean Penn took home the Oscar for Best Actor in a Leading role  his work on Gus Van Sant's film "Milk" about a gay rights activist in San Francisco. The award was the second to go to 'Milk' after the film's writer Dustin Lance Black won the award for Best Original Screenplay earlier in the night. Penn, 48, picked up the second Oscar of his career, the first being his 2004 win for his lead role as a grieving father in "Mystic River." "You commie, homo-loving, sons of guns," the sharp-tongued Penn told the audience as he collected his award. "I did not expect this and...I know how hard I make it to appreciate me."

Sean and ex-wife Madonna met at an after-show party. Madonna, 50, praised 48-year-old Penn's winning performance in Milk. But Penn gestured at the singer's new love, model Jesus Luz, 22, and said: "Thanks. Another kid already?" Well said Sean and well done on your Oscar.
