EXCLUSIVE: Megan Fox and Actor Brian Austin Green Call Off Engagement

Megan Fox and fiance Brian Austin Green have split, Usmagazine.com has learned.

"The relationship had run its course," an insider tells Us exclusively. "It's completely amicable, and they are remaining friends."

Fox, 22 (who’ll reprise her role as Mikaela in this June’s sequel Transformers: Revenge of the Fallen), and Green, 35 (a regular on Fox's Terminator: The Sarah Connor Chronicles), now “are both focusing on their careers," the source adds.

Us Weekly has more details on their shocking split. Pick up the new issue, on stands tomorrow.



The couple -- who have tattoos of each other's names -- met in 2004 and, as Us first reported, got engaged in November 2006.



Last November, Fox told Us that the wedding plans were still on.

"It's not going to be a big wedding," she told Us at a GQ bash. "I'm not one of those girls. If it happens, it will be very low-key and quick and unplanned."



She said she and Green -- who has a 6-year-old son, Kassius, from a previous relationship -- haven't talked about wanting more kids.

"I feel like I need to set my career and do a movie other than Transformers," she said. "Then I’ll explore family."
