Megan Fox is still 10 pounds away from her pre-baby weight after the Sept. 27 birth of her first son, Noah, but she's in no hurry to lose it.
"I only gained 23 pounds when I was pregnant and I'm still 10 pounds heavier, but I don't want to kill myself trying to get back into shape because it's not a priority right now," she says in the Dec. 7 issue of the U.K.'s Daily Mirror. "I'm too in love with Noah and I don't want to be away from him. I just want to be home."
Fox, 26, also explains why she and husband Brian Austin Green, 39, recently decided to hire a nanny. "Having an infant is difficult. It's a lot of work and I didn't hire any help because I overestimated my own abilities. I had no idea how difficult babies could be, so Brian and I were exhausted," the star of This Is 40 says. "You never sleep and you're awake all night and your entire life is devoted to this little thing that needs you constantly. And I love it. It's what I've wanted to do since I was a little girl."
The new mom continues, "I always wanted to mother things and I constantly had a doll I was taking care of. I don't receive the same satisfaction from my career as I do from being a mother so I'm really happy. But two weeks ago I said to Brian, 'We have to get a night nurse or we're going to get a divorce because someone's got to sleep in this house or we're going to kill each other.'"
Fox -- stepmom to Green's son Kassius, 10 -- tells the Daily Mirror that she'll be shying away from sexier roles now that Noah is in her life. "It changes your perspective about being overly sexual in a film when you have a baby. 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," the actress says. "So that will deter me from making some of the choices I made before."
Of course, Fox's wild days are far behind her. "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," the Jennifer's Body star admits. "But now, maybe because of getting married and wanting to have a family, I've come back full circle."
