The 41 year old mother of three is back in front of movie and magazine cameras.

 'Just when you think you're getting your s**t together, someone says, "When is your baby due?" I had Henry on my hip, and it was like, "This is my baby."

'It hurt my feelings so bad. I think the second-meanest thing you can say to somebody is, "You look tired." Why do people say that? Just tell me I look like a mom! Don't tell me I look tired.'

Attributing her youthful appearance to her cameraman husband of six years, Julia tells the magazine: 'The key to beauty is always to be looking at someone who loves you, really.

'One of my favourite things about my children right now, even Henry, who can't say all the words… sometimes he'll see me and go, "Ma-ma!" and throw himself on me. Or Finn says he likes my earrings. Or Hazel will say, "You look pretty, Mama," first thing in the morning.

'And I realise, that's all my husband. They're seeing the things that he does and the way that he shares his feelings with me, and the way that I share my feelings with him.

'The coolest thing you can do for your children is to love each other in their presence.'

After a few years out of the spotlight to raise her three children, twins Hazel and Phinnaeus, four; and baby Henry, 20 months, Julia is back on the big screen in two upcoming movies Duplicity and Fireflies In The Garden.

Long regarded as the queen of romantic comedies due to roles in Pretty Woman, Notting Hill and My Best Friend's Wedding, Julia believes it's inappropriate for women of her age to be starring in the genre.

She tells Allure: 'I don't believe that somebody would go to a movie and look at me and say that I have (those) problems anymore.

'I mean, who wants to see me twirling my hair, going, "Oh, I wish he loved me?"'
