Sean Penn was so excited he had experienced his first same-sex kiss with Milk co-star James Franco - he immediately texted gay icon Madonna to boast.

Penn stars alongside Franco in the forthcoming biopic of San Francisco's first gay Mayor Harvey Milk, in which the pair play lovers. And after wrapping their first gay smooch scene, Penn wanted to tell his ex-wife Madonna about his risqué antics.

Franco tells Britain's Daily Mirror newspaper, "After our kiss, Sean texted Madonna and said, 'I just popped my cherry kissing a guy. I thought of you. I don't know why'."
