The 26-year-old told the Mirror: ‘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.

‘So that will deter me from making some of the choices I made before.’

The Robot Chicken star also revealed the reason she decided to name her son after the biblical legend who famously built an ark to avoid an apocalyptic flood.

The Tennessee native said: ‘ 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.’

While she is going to be more choosy in future about her roles, she revealed she is already nearly back to peak condition.

She said: ‘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.

‘I’m too in love with Noah and I don’t want to be away from him. ‘I just want to be home.’

She is dedicated to put in as much work looking after the baby as possible, and amazingly even tried looking after the baby without any help initially.

However this was not working for her and husband Brian Austin Green, so they have now hired a night nurse for two nights a week.

She said: ‘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.

‘You never sleep and you’re awake all night and your entire life is devoted to this little thng that needs you constantly.

‘And I love it. It’s what I’ve wanted to do since I was a little girl.

‘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.”‘

However she also admitted that she worried about the effect having a child would have on her career.

She said: ‘It’s scary because unfortunately women in the film industry don’t seem to hold their value as they get older so it’s scary for all of us.

‘It’s the same thing for actresses. I’m 26 but already time is a tickin’.’
