Megan Fox Post-Baby Interview: 'This Is 40' Star Talks Bikinis, Religion (VIDEO)

Megan Fox might have once been named the "Sexiest Woman in the World," but the new mom is turning over a new leaf and leaving her provocative persona behind.

Fox gave her first post-baby interview to the U.K.'s Mirror, revealing her evolved thoughts on wearing bikinis and embracing religion.

Since taking on the role of mom when she gave birth to her first child in October, Fox says she will change how she chooses roles from now on. "It changes your perspective about being overly sexual in a film when you have a baby," she told the Mirror. “I’m going to be more cautious about choosing films because I’m already thinking about when he’s in school and his friends are going to be showing him my photo shoots with me in a bikini and he’s going to be horrified."

Fox also discussed returning to her religious roots.

The 26-year-old was born and raised in rural Tennessee and, after a rebellious period, has decided to return to her religious roots. “I went through a stage in my early 20s when I was very rebellious against how I was raised and I wasn’t worried about faith or religion but now, maybe because of getting married and wanting to have a family, I’ve come back full circle," she told the Mirror. Her son name, Noah, derives from the Biblical character who built an ark during the Great Flood.

Fox and husband Brian Austin Green announced the arrival of their son in a religious-tinged Facebook post, saying: "We are humbled to have the opportunity to call ourselves the parents of this beautiful soul and I am forever grateful to God for allowing me to know this kind of boundless, immaculate love."

Despite her new conservative attitude, Fox does strip down in the upcoming Judd Apatow flick, "This Is 40," out Dec. 21. The new mom romps around a pool in a bikini and flaunts it all in a pink bra and underwear.
