The 29-year-old actress - who revealed she's pregnant with her third child when she debuted her baby bump in a tight-fitting Versace dress at CinemaCon in Las Vegas on Monday (11.04.16) - has sons Noah, three, and Bodhi, two, with her estranged husband Brian Austin Green and doesn't "care" about celebrating the little milestones because she's happy as long as her family are well, "mentally emotionally, spiritually and physically."

The brunette beauty turns 30 on May 16 and won't be celebrating the occasion with a lavish gathering of friends.

She declared: "I'm not very ceremonious. Even with my own kids, until they ask me for birthday parties, we don't do big birthday parties. I just don't care. It's just a day.

"I'm practically already 30, what's the difference? It's like a month away. What really changes? As long as everything is holding up well, then I don't care how old I am. By everything, I meant mentally, emotionally, spiritually and physically."

Meanwhile, the 'Teenage Mutant Ninja Turtles' star doesn't allow her children to watch much "television and movies" because she thinks it is "really bad" for their brain development.

She said: "Noah is too young and I try to keep them from television and movies for the most part. 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."

And Megan's kids don't even know she's a famous movie star.

She added to E! News: "They have no idea what I do. 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. "
