The Hollywood actress, who has found fame on the small screen and in huge blockbuster movies, confessed that she has never let her kids - Noah, three, and Bodhi, two - watch her films because she doesn't want their brains to mess up.

Megan was promoting the upcoming Teenage Mutant Ninja Turtles sequel at WonderCon in Los Angeles, California, on Saturday (26Mar16), and admitted it was hard to not let her sons become a "nerd" like she was.

"I try not to expose them to technology,” she said. "It’s hard to make them super nerds if I don’t let them watch television or movies, or get on an iPhone or an iPad.

"So right now, I’m making my kids into artistic nature-hippies. We’ll see what happens. At some point, they’ll choose what they want to be."

The 29-year-old, who split from the father of her children, Brian Austin Green, last year (2015), said that she disapproves of parents using technology as a "babysitter" while they try to get errands done.

She explained that banning technology is "only challenging as a parent because so many people use that as a babysitter, and they’re like, 'I just need an hour to clean the dishes - watch this movie or play Angry Birds on my phone.'

"It’s actually really bad for their brain development, and I’m trying to breed, like, superheroes. I don’t want them to get f**ked-up brains. So I just suck it up, and it’s hard, and one of us is always doing something. We don’t get a lot of rest time, but I know it’s better for them."

Megan shared with what she dreams her children will grow up to be, and admitting that she longs for them to be artistic and musical.

"I would love one of them to be a painter or a poet and, like, wear scarves and walk around Paris, like angsty,” she laughed.

"Then I would like one to be a musician, maybe. Their dad Brian plays jazz drums and is a good musician. So I think one of them is going to have the spark for that."

Teenage Mutant Ninja Turtles: Out of the Shadows, is due to be released in the U.S. on 3 June (16).
