The Beverly Hills, 90210 star confirmed the couple - who wed in 2010 - have decided to go their separate ways.
On his podcast ...with Brian Austin Green, the actor, 46, said: “I wanted everyone to hear everything from me, and this is it. Neither one of us did anything to each other. She’s always been honest with me. I’ve always been honest with her.
“We’ve had an amazing relationship. I will always love her. And I know she will always love me...”
And Brian has vowed that he and Megan will remain good friends and co-parent, well for the sake of their three children - Noah, seven, Bodhi, six, and Journey, three.
Brian said Fox, 34, confided in him when she suggested time apart.
“She said, ‘You know what, I realised while I was out of the country working alone, that I feel more like myself and I liked myself better during that experience. And I think that’s something that might be worth trying for me,’” he said.
“I was upset about it, but I can’t be upset at her and I wasn’t upset at her because she didn’t ask to feel that way.”
Rumours floating around suggests Fox and rapper Machine Gun Kelly have ‘definitely hooked up’ following the split.
But Brian says the duo are ‘just friends’.
