The "To Rome With Love" star, who always loves to worry about everything in her life, said since giving birth to her only child she is not concerned about meaningless aspects of her life that used to bother her before parenthood.
"For me, having my son means I worry less. I've always loved to worry - ever since I was a little girl people would tell me I worry too much. But these days I really have to pick my subjects to worry about because there are only so many hours in the day.
"You have less ego because you are not number one any more. The things you used to believe were important - such as what people think of you, whether they like you - you realise they are not so important, not really," she said.
The 38-year-old brunette beauty said she constantly feels tired due to the demands that come with having a baby. "Now, if you ask me if I am rested, I will say no, because I am not - I am tired all the time. But happy? Absolutely. I feel very calm, very focused, very much in a good place."
