According to multiple reports, Megan Fox is pregnant with her third child!

The actress showed off a noticeable baby bump on Monday while posing next to costar Will Arnett at CinemaCon in Las Vegas. The father is believed to be the 29-year-old's estranged husband Brian Austin Green, whom she filed for divorce from in August, but that has not been confirmed.

The duo is already parents to sons Noah, 3, and Bodhi, 2, and though they split after five years of marriage, they've been spending a lot of time together recently.

As Life & Style previously reported, the former couple grabbed a bite to eat at the Sweet Butter Cafe in Studio City, Calif., early last month.

Congrats to the brunette beauty!
