When Megan Fox debuted her baby bump at CinemaCon on Monday, her Teenage Mutant Ninja Turtles: Out of the Shadows costar Will Arnett was by her side to promote the film.
But because the brunette beauty, 29, is currently in the middle of a divorce from husband Brian Austin Green, fans began speculating that Will, 45, could be the child's father, which the actress quickly shot down with a hilarious Instagram post.

After Megan confirmed that neither Will nor former costars Shia LaBeouf and Jake Johnson were the father, Amy Poehler's former hubby feigned shock over the announcement.

"She said I'm not the father? That's a big surprise to me," Will joked to ET.
TMZ has since reported that Brian, 42, is the baby daddy, though the duo are allegedly going ahead with their divorce despite the pregnancy.
The couple, who split in August, is already parents to sons Noah, 3, and Bodhi, 2. The Beverly Hills, 90210 actor also has a son, Kassius, from a previous relationship.
