Megan Fox is pregnant and expecting her third child, according to reports.

The 29-year-old is expecting bub number three, eight months after filing for divorce from husband Brian Austin Green, Us Weekly reports.

The pair separated six months before divorce papers were filed, but have remained amicable co-parents to children Noah, 3, and Bodhi, 2, leading many to speculate former 90210 star Green could be the father of Fox's third child.

The Transformers and Teenage Mutant Ninja Turtles star and her 42-year-old beau were together for 11 years before their split, which sources say was in part due to her career demands.

"They fight about her career," a source told Us Weekly last year. "She was obsessed with getting roles."

Fox will probably pay Green spousal support as part of the divorce settlement, TMZ reports.

There's a large income difference between the two stars - mainly because of a terrible car accident the pair suffered.

Back in December 2014, Fox and Green were involved in a head-on collision with a drunk driver that left Green with a bad case of vertigo.

Since the accident, Green hasn't been able to work.
