The pair announced they had separated on Thursday (29Aug13).
A statement from their representative reads: "Tamzin Outhwaite and Tom Ellis are sad to confirm they have separated. They continue to support each other as parents and will remain friends. They ask for sensitivity at this difficult time."
The couple met through mutual friend James MCAvoy in 2005 and wed a year later (06). They have two young daughters, Florence, four, and one-year-old Marnie Mae.
Ellis has starred in Doctor Who and hit U.K. comedy Miranda, while Outhwaite appeared in British soap opera EastEnders.
