“They decided on it six months ago,” a source told the publication.
The magazine were told that the couple's relationship has had a lot of issues. No exact reason has been given about why they decided to go their separate ways. But, "things have been rocky," a source told Us Weekly.
PEOPLE have confirmed the split through an unnamed source, but they did give us a little hope this wonderful couple might get back together... "anything could happen in the future".
The A-list actress and her partner - best known for his part in Beverly Hills, 90210 - have been together for 11 years and their split has come as a shock to their many fans.
They have two children together - two-year-old Noah and 18-month-old Bodhi.
No word from the couple, but if it is true, we're very sad to hear about the split.
How do you feel about the split?
