Brian Austin Green has confirmed he and wife Megan Fox have separated after nearly a decade of marriage.
Beverly Hills, 90210 star Green, 46, and Hollywood actress Fox, 34, tied the knot in 2010 and have three sons together.
Green revealed their break-up in the latest episode of his podcast, saying they have been "trying to sort of be apart" since the end of last year.
"I will always love her," Green said. "And I know she will always love me and I know as far as a family what we have built is really cool and really special."
Green said the family would still go on holiday together, before becoming emotional and describing Fox as "my best friend for 15 years".
He said: "It sucks when life changes and something that you're used to, that you've been doing for 15 years, you try and not get rid of but you change.
"There's the unknown aspect, there's that pit in my stomach. I really don't want Megan and I to be at odds.
"She's been my best friend for 15 years and I don't want to lose that."
Green also referenced pictures of Fox with the rapper Machine Gun Kelly, whose real name is Colson Baker.
He said: "She met this guy, Colson, on set. I've never met him. Megan and I have talked about him. They're just friends at this point."
Green added: "I trust her judgement, she's always had really good judgement. I don't want people to think her or he are villains or that I was a victim in any way."
Green and Fox, whose film roles include the Transformers franchise, Jennifer's Body and Above The Shadows, started dating in 2004, when he was 30 and she was 18.
They became engaged in 2006 and were married in Hawaii in June 2010.
