Megan Fox’s appearance at CinemaCon set tongues wagging when she highlighted a very visible baby bump in a tight black dress while promoting Teenage Mutant Ninja Turtles 2.  Noting that the actress had filed for divorce from her husband, Brian Austin Green, in August of 2015, everyone wondered – who’s the father?

The actress posted a tongue in cheek response to the rumors swirling around her pregnancy. She took to her Instagram page, sharing a photo collage of her with several past co-stars including Will Arnett, Shia LaBeouf, and Jake Johnson, with the caption, “#notthefather.”

Shortly after, a source confirmed to People that “Green is ‘of course’ the father and that the pair ‘never stopped loving each other and they will never stop being devoted parents to their boys.'” People also reported that the couple is “very excited” about the pregnancy, though it was not planned, and that they are working on their marriage.
