Megan Fox has said her attitude to Hollywood has changed since becoming a mum and has revealed how she has made up with film director Michael Bay.

The 28-year-old sex symbol said that while she may have been "a little bit overwhelmed" by Tinseltown earlier on in her career, her approach to work has changed since becoming a parent to her two young sons - Noah, two, and eight-month-old Bodhi - with husband Brian Austin Green.

The actress said: "I think it's a mistake for anyone to make it [Hollywood] their life, because there's nothing real about it. It's surreal and false."

Like many parents, the actress, whose breakthrough role came as Mikaela Banes in Michael Bay's 2007 action movie Transformers, is trying to strike a balance between spending as much time as she can with her children, while also enjoying her career.

And though she previously had a public falling out with Bay, where her comment that his working style was like "Hitler" or "Napoleon" ended up with a prompt firing from the Transformers franchise, now, they're both fully supportive of each other's situations.

"[Michael] was really on my side," explained Megan, who has reunited with him on the big screen outing of Teenage Mutant Ninja Turtles [Bay's a producer on the movie], in which she plays tenacious reporter April O'Neil.

"At one point, when we were negotiating the contract [for Turtles], they wanted us to work six-day weeks, and I was a new mom and was like, 'I can't do this'.

"He [Bay] was the one that went, 'No, no, no, we're not going to ask her to do that. She gets two days off. She has to have time to be a good mom', so we've really come full circle and I have a good relationship with him now."

Although her second pregnancy prevented her from doing some stunts, she did "as much as possible" on the film, which sees the four outcast Turtles take on a ferocious crime squad in New York.

For Megan, a lifelong fan of the children's TV series of the same title, the chance to play the "iconic" April, who helps the Turtles bring the criminals to justice, was too good an opportunity to miss.

"I wanted this part really badly," she said. "April's a kind of a Joan of Arc in my mind, someone who believes in doing whatever you can to accomplish what's right."
