MEGAN Fox has vowed never to film an X-rated scene again in case it affects her children.

The actress is one of the most lusted after leading ladies in Hollywood and has played a series of scantily clad characters since rocketing to fame in 2007’s Transformers.

She was a sex worker in 2010 film Jonah Hex, starred in Eminem and Rihanna’s saucy Love The Way You Lie video the same year and kissed Amanda Seyfried’s character in 2009’s Jennifer’s Body.

But since becoming a mum to sons Noah, three, and Bodhi, two, the 29-year-old has turned down some of the raunchier roles she has been offered.

In an exclusive chat with The Sun, Fox, who is expecting her third child, explained: “There are just certain things boys should never see their mothers do.

“There are some good projects I’ve read that are with talented people, talented directors, but the things the women are required to do in the movie are things I can’t have my sons ever know or see. I was offered a project that’s coming out on HBO that centres around the life of a prostitute and it has very graphic sex scenes — things you would see in a pornographic film — and those are things that are degrading to the woman who’s playing the character.

“It’s up to the mother to determine what she thinks her children can handle seeing or not. I don’t think my children should ever see me doing some of that stuff. I don’t think my boys could handle that. They can’t separate the experience from the reality from the art. It gets very confusing when it’s your own mother.”

Last month, Fox revealed she was pregnant with estranged husband Brian Austin Green’s baby, despite previously planning to divorce him.

Instead she has now reunited with the 42-year-old, who is the father of her two sons, and admitted they are moving out of LA city to focus on raising their brood, which also includes her stepson Kassius, 14.

Hinting that the child she is expecting could be another boy, she added: “The third one will have the best experience of us as parents. And he also has two older brothers who are also going to take care of him.”

Despite her worries about being sexualised on screen, Fox — who reprises her role as reporter April O’Neil in this month’s Teenage Mutant Ninja Turtles sequel — was dismissive of those who criticise her acting.

Admitting she had not worked hard for her fame, she said: “I’m not like a silly, stupid little actress but I don’t care if people only want to hire me to look pretty. In Hollywood your time is limited and I’m not passionate about it.”

Instead of an Oscar on her mantelpiece, Fox has gongs including Choice Hottie of the Year and a Worst Supporting Actress Razzie.

But she said: “It is what it is. I don’t care. I feel like if I was really hung up on critical acclaim or people’s opinions then I would be more pressured, I would strive harder to disprove such a stereotype. But sometimes you just get pigeonholed. I have fun most of the time making movies, and that’s the main objective because it’s just a job. Where I’m from in Memphis, women are damsels and ladies and they’re gentle or whatever. I was very fiery and no-nonsense.

“I put that out there instantly in this industry because it’s important for people to understand that I am not a dumb girl, I’m a very clever girl and you’re not going to get anything over on me.”

She is so disenchanted with the industry that turned her into a superstar that she admits she may one day quit.

“I’m trying to figure out what I really want to do with the rest of my life because Hollywood is not a land where you can work until you’re elderly, when you’re a woman especially,” she said.

“It’s not something I’m necessarily passionate about, so I’ve asked myself this question for the last few years, ‘What is it that I’m here for and where are my passions?’ I got to this place without any effort, I’m not very ambitious. It’s strange I keep getting offered these movies that are big, tent-pole franchises. So I’ve always wondered why it is happening to me when I put no effort into it.

“There has to be a reason. So I’m just trying to figure out exactly what that is and what that means. I’m not trying to deny it or reject it, I just have to incorporate it with other things I like.”

Away from work, Fox was coy about her reunion with Green.

She once confessed her man-eater image was at odds with reality as she had only ever had sex with two men — Green and her childhood sweetheart.

She said: “I can never have sex with someone I don’t love, ever. The idea makes me sick. I’ve never even come close to having a one-night stand.”

Her Transformers co-star Shia LaBeouf claimed they had a romance, with US magazine Details saying he nodded “affirmatively” when asked if they hooked up.

He said Fox quit the franchise because director Michael Bay made her “feel like a prostitute”, saying: “Megan developed this Spice Girl strength, woman-empowerment stuff that made her feel awkward about her involvement with Michael, who some people think is a lascivious filmmaker, the way he films women.

“Mike films women in a way that appeals to a 16-year-old sexuality. She never got comfortable with it. This is a girl who was taken from complete obscurity and placed in a sex-driven role in front of the whole world and told she was the sexiest woman in America. And she had a hard time accepting it.”

Talking about turning 30 on May 16, Fox hinted her love of stargazing had made her get going “in the right direction” and reunite with 90210 star Green.

“There’s something in astrology called your Saturn return. Saturn is the planet of karma and responsibility and life lessons take 30 years to orbit your chart, so usually everyone in their 30th year has some self-realisation to ensure they’re going in the right direction,” she said.

“Or people who are extremely lost have some sort of a breaking point, some sort of a low that they hit around that year. That’s definitely what has happened for me, getting to a point where I can’t deal with things that feel unnecessary.”
