After rumors circulated that the divorce proceedings were sparked by Sean Penn getting jiggy with Sienna Miller... and two other chicks, TMZ is reporting that the Penns have filed paperwork to dismiss their divorce.

The couple were seen together at an Eddie Vedder concert last night in San Francisco and reportedly Sean went on stage to dedicate a song for Robin's birthday.

Penn and his wife Robin Wright Penn began dating one year after Penn ended his four-year relationship to Madonna in 1989, meeting on the set of the 1990 thriller "State of Grace."

Wright is best-known for her role as Princess Buttercup in the 1987 hit, The Princess Bride. Sean Penn's breakout role was in Fast Times at Ridegmont High. The Penns have two children together.
