So much for 'Fringe' benefits: Former co-stars Anna Torv and Mark Valley have ended their marriage, PEOPLE has confirmed.

The notoriously press shy couple, who met on the set of the hit Fox series, were married in Dec. 2008 in a quiet ceremony after just a few months of dating. The news was revealed to the press a few months later.

"I think [Anna] is just a fantastic actor and I really like working with her," Valley told the AP at the time. "She's my favorite on the show, to be honest with you."
