Sean Penn is known for his ability to get into character, but he’s through with one role: husband. Penn has filed for legal separation from his wife of 13 years, actress Robin Wright Penn. The couple’s had a rocky past: Penn filed for divorce in 2007 but later dismissed the suit. A few days later his 43-year-old wife filed for divorce, too. The couple appeared to reconcile last April, when they asked for the divorce petition to be dismissed, but Penn had fans whispering when he failed to thank his wife during his acceptance speech at the Oscars this winter. He later told Oprah Winfrey that he wanted to focus his speech on the film’s professional team. Penn won the Oscar for Best Actor for his starring role in Milk; this will be his second divorce—his first, of course, was from Madonna.
