Megan Fox has responded to speculation about the paternity of her unborn child with a tongue-and-cheek Instagram post.
The Teenage Mutant Ninja Turtles star, who is pregnant with her third child, joked about who the father is on the picture sharing site.
“#notthefather,” the actress, 29, wrote alongside a collage of photos of herself with her former costars Shia LaBeouf (Transformers), Will Arnett(Teenage Mutant Ninja Turtles) and Jake Johnson (New Girl).
The joke comes after the actress debuted her baby bump at Cinemacon on Monday and caused fans to speculate as to whether her estranged husband, Brian Austin Green, is the father.
The divorced mother of two was at Cinema Con to promote her new film, Teenage Mutant Ninja Turtles. People Magazine has reported that several sources have confirmed the pregnancy.

She filed for divorce from Green in August 2015 after five years of marriage and 11 years together, citing irreconcilable differences, however reports at the time said the split was "very amicable" despite the absence of a prenuptial agreement.
However the couple have been spotted together several times in recent months, leading to speculation that a reconciliation may be on the cards.
