Ben Stiller, the Hollywood actor, and his actress wife have announced they are separating after a 17-year marriage.

Christine Taylor, 45, and Mr Stiller, 51, released a joint statement on Friday, announcing the break-up and requesting privacy.

The couple, who have often starred alongside each other in films, had been together for 18 years. They married in Hawaii in May 2000.

They have two children together - a 15-year-old daughter, Ella, and an 11-year-old son, Quinlin - who both made cameo appearances in Megamind, a 2010 animated film.

“With tremendous love and respect for each other, and the 18 years we spent together as a couple, we have made the decision to separate,” their statement read.

“Our priority will continue to be raising our children as devoted parents and the closest of friends.”
