The hot mom - who is busy at work promoting her new film, This is 40 - shrugged off losing the last of the baby weight she gained while pregnant with son Noah Shannon Green, whom she and husband Brian Austin Green welcomed on Sept. 27.
"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," Us Weekly reports she told the U.K.'s Daily Mirror recently. "I'm too in love with Noah and I don't want to be away from him. I just want to be home."
But it turns out even movie stars need a little help in the infant department. Fox admitted that after a few weeks of trying to weather those late night feedings alone, she and her husband got help.
"Having an infant is difficult," she said. "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," she said. "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."
She continued, "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.'"
