Megan Fox plays a guessing game about who her baby daddy is

Cape Town – Megan Fox made everyone tilt their heads when she walked the red carpet at the opening of CinemaCon on Monday night sporting a baby bump.

The Teenage Mutant Ninja Turtles actress kept mum on expecting her third child but has now confirmed it with a fun guessing game as to who the baby daddy is.

Getting in on the joke, Megan shared a collage of her male co-stars on Instagram with the caption: “#notthefather (sic)”

Jokes aside, E! News reports her estranged husband, Brian Austin Green, 42, is the father, and, as a result, the divorce "will likely be put on hold for a while". 

A source said: "This pregnancy was not planned, but when they found out they were extremely happy.

"Megan and Brian love being parents. They are working really hard to be together and one unit--not only for their children, but also for each other. They are looking forward for the arrival of their new baby."
