Megan Fox caused a frenzy on social media after she was seen on the red carpet for CinemaCon on Monday, showing a baby bump. Fox filed for divorce from her estranged husband, Brian Austin Green, in August.

The photos of a pregnant Fox left social media users clueless as to who the father of her third child was. Fox was seen wearing a Versace dress showing her baby bump as she promoted her new movie “Teenage Mutant Ninja Turtles: Out of the Shadows” with co-star Will Arnett. Fox had filed for a divorce after being together with Green, with whom she has two sons, for 11 years. The couple separated six month before filing for divorce.

However, in the recent months, Green and Fox have been spotted together several times and have reportedly been co-parenting their children happily, People magazine reported.

“They’re on friendly terms for the sake of their kids,” a source told Us Weekly after Fox filed for divorce.

In March, Fox and Green were seen leaving Sweet Butter Café in Studio City, California, without their children. The two have also been spotted with their children on numerous occasions, Us Weekly reported.

According to a report by Hollywood Life, Fox and Green were also seen last November grabbing a cozy lunch without their sons and seemed flirtatious toward each other. Fox’s last major media appearance was on “Ellen” in February, without a visible baby bump, the report added.

Fox has not confirmed or denied the pregnancy so far.
