Pic! Madonna and Sean Penn Reunite at 'SecretProjectRevolution' Premiere

A reunion between Madonna and ex-husband Sean Penn ended with friendly fireworks on Tuesday night, when Penn gave Madge a hug and a kiss on the cheek at her “SecretProjectRevolution” premiere in New York City.

The exes, who were married from 1985 to 1989, chatted casually at the party and even posed for pictures. They both happen to be single these days.

The star-studded affair, with guests like Lindsay Lohan, Anderson Cooper and Zac Posen in attendance, was the debut of Madonna's 17-minute film with director Steven Klein. Watch it below!

"My goal is to show by the example of 'secretprojectrevolution' my creative commitment to inspire change in the world through artistic expression," she said in a statement. The movie, which debuted guerrilla-style around the world, stars Madonna as both a prisoner and jailer.

As part of the kickoff, Madonna and son Rocco Ritchie, 13, took the stage for a dramatic skit involving policemen arresting the “Girl Gone Wild” singer. Rocco's father is another of Madonna's ex-husbands, director Guy Ritchie.
