Julia Roberts has admitted she’s finding motherhood tiring. The actress, who gave birth to twins Phinnaeus and Hazel last November, says the sleepless nights are taking their toll. Speaking at a benefit concert this week, she said: "I am tired. I get up in the middle of the night so they can sleep."

Last month, it was revealed Julia had started meditating to help her cope with the pressures of bringing up her twins. Julia, who is married to cameraman Danny Moder, was quoted as saying: "I didn’t realize that I would get no sleep at all. I’m so sleep-deprived, I can’t even stand. I need to sit down all the time. The only way I can get through it is to meditate."

Julia also says said she was shocked at how much motherhood has affected her looks, saying, "There are days when I look at myself in the mirror and I’m so fat and bedraggled I don’t even know who I am."
