Megan Fox talks motherhood as sources confirm pregnancy

Megan Fox has opened up about motherhood amid rumours she's expecting her third child.

The 29-year-old actress sparked allegations she's pregnant after attending Las Vegas' annual CinemaCon to promote her new film, Teenage Mutant Ninja Turtles: Out of the Shadows, wearing a tight dress which showed what appeared to be a baby bump.

Since the event, multiple sources have confirmed the pregnancy to People, although the identity of the child's father has yet to be revealed. It is thought it may be Megan's estranged husband Brian Austin Green, as the pair have been seen out and about together in recent months.

Megan is already mother to sons, Noah, three, and Bodhi, two, with Brian, and spoke about her parenting experiences during an interview with E! News on the red carpet at CinemaCon.

She admitted that despite her prolific acting career, her boys are oblivious to what she does for a living.

"They have no idea what I do," she laughed. "Somebody at their school will tell them eventually but then it won't mean anything because they've been around it their whole lives so they'll be like okay. I'm still embarrassed of my mom!"

Megan has always been vocal about her opinions when it comes to raising her children. And she explained that she does her utmost to keep her boys away from technology as much as possible.

"Noah is too young and I try to keep them from television and movies for the most part," she explained. "I think any sort of screen - whether it's television, iPad or iPhone - is really bad for their brain development so I try to remove that from their lives and I also want to deter them from ever being on social media because I think it's detrimental to a child's self-esteem.

"I have lots of opinions on this! I do let them watch Pixar movies. We do stuff like that. We watch Peter Pan together."
