New Girl Season 5 Megan Fox Pregnant: Is Ex Brian Austin Green Daddy Of Her Third Baby?

New Girl Season 5's Megan Fox walked the red carpet at the opening night gala of CinemaCon at Caesars Palace in Las Vegas on Monday, April 11, where the Teenage Mutant Ninja Turtles actress showed off her baby bump. So is Brian Austin Green the father of Fox' unborn child?

The bump was glaringly obvious in her skintight black dress under a leather jacket, and it was particularly noticeable as she posed alongside her TMNT co-star Will Arnett.

The 29-year-old actress is already mom to three-year-old Noah and two-year-old Bodhi, with her ex-husband Brian Austin Green. Fans took to Twitter to express their surprise at the unexpected news, and they all shared the same sentiment. Everyone wants to know who the father is!

In August of 2015, the star filed for divorce from Brian Austin Green, her husband of five years citing "irreconcilable differences." Per court documents, their divorce is still pending.

Despite the divorce news, it seems as though the two have been spending plenty of time together as of late. In fact, both were seen on multiple family outings around Los Angeles with and without their two kids.

However, there has been no confirmation that Green is the father, and no word of reconciliation, so fans aren’t accepting the idea that her ex-husband is the father.

Back in 2014, Fox opened up to Men's Health about her marriage to Green.

"You can't live in a fantasyland and think that everything's going to be perfect all the time. You will go through phases where you're just not getting along. You're not communicating well. That's going to happen, and it's going to feel impossible to you sometimes. It might not even make sense to you sometimes. Arguments are normal," she explained.
