And the endless summer of celebrity splits continues...

A source revealed to Us magazine that Megan Fox and Brian Austin Green have split up after 11 years together, five of which were as a married couple.

The source added that the couple made the decision to split "about six months ago" and that "things have been rocky," although the reason behind the breakup remains a mystery. The last time the two were photographed together was back in June as they were having lunch in Beverly Hills.

The couple have two children, Noah, 2, and Bodhi, 18 months. Green also has a son, 13-year-old Kassius, from a previous relationship.
