Who Is The Father Of Megan Fox's Third Baby?

Megan Fox was spotted on the red carpet for CinemaCon on Monday, but what created a sensation was her baby bump.

Last August, Fox had already filed for divorce from her estranged husband, Brian Austin Green. She had been with him for 11 years and had two sons. The couple separated six months before they filed for divorce.

And now, she seemed to be having her third child.

But who could be the father?

Fox was wearing a Versace dress that revealed her baby bump, even as she promoted her new movie, "Teenage Mutant Ninja Turtles: Out of the Shadows" with co-star Will Arnett.

In recent months, Green and Fox were seen together several times, reportedly co-parenting their children, People magazine reported.

After she had got married, she told the media that she did not envisage divorce. "Brian and I have done everything you can do to ruin a relationship and we still love each other," the former "Transformers" star said. "I don't want to be boastful and say that we would never divorce, but I can't imagine a scenario we couldn't work through."

Still, they remained amicable and on good terms with each other. "They're on friendly terms for the sake of their kids," a source told US Weekly  after Fox filed for divorce.

Last month, they were spotted emerging from Sweet Butter Café in Studio City, California, without their sons. They have been seen with the children in a number of places. Last November, they were seen sharing a lunch and some closeness without their sons, flirting with each other on the table. Her last major media show was on "Ellen" in February, but she did not show a visible baby bump, added the report.

So far, Fox has not confirmed or denied the pregnancy.
