'X-Men' Star James Marsden's Wife Files for Divorce

"X-Men" star James Marsden's wife has filed for divorce, TMZ has learned.

Lisa Linde cited irreconcilable differences. She's seeking spousal support and joint legal and physical custody.

A rep for James tells TMZ, "This was a mutual decision. They are committed to raising their kids together and remain great friends."

The couple married in 2000 and have two children -- a son and a daughter.

Lisa filed for divorce on September 23rd. So this is interesting ... TMZ got video of James at 4:30 AM that morning, outside the Papaya King hot dog shop in New York, singing with a bunch of friends.
