Rachel Weisz admits motherhood makes her want to “scream”. The Lovely Bones actress – who is engaged to director Darren Aronofsky – says being a parent to three-year-old Henry is “delicious” but admits she needs her friends for support when family life gets too stressful. She said: “I think one of the things that mothers aren’t allowed to talk about enough to one another… is the times when you’re pulling your hair out at home with the kids. “Those moments when everything is crashing in and you feel like you’re going to scream. “It doesn’t make us less good or less human, just real. I think there is sometimes too much pressure on us to be perfect parents, to be empathetic and loving all the time. Every woman needs a good girlfriend to be able to turn to and say, ‘I just can’t deal with it all today.’ “Because even though children are the most precious things in the world, they are also sent to test us. I think women are already stretched and pressured to be perfect, and it kind of drives me crazy.” Despite her confession, the 39-year-old star says she has “never been happier” since having Henry and claims he has improved her life in so many ways. She added to Redbook magazine: “I find I can get a lot more done since I’ve had Henry. Suddenly, in 45 minutes, you can get twice as much done as you once did. I’ve become a lot more organised. “And I’m a much happier person since I’ve had Henry, and much more balanced. I feel I have an ultimate purpose beyond anything else in my life.”
