The on-again/off-again marriage between Sean Penn and Robin Wright Penn appears to be headed toward on-again.

The couple withdrew their divorce petition on Tuesday, one day after Penn reportedly jumped on stage at an Eddie Vedder concert and dedicated a song to Wright Penn.

They were married in 1996 and filed for divorce last December. - J.R. Whalen
