Salma Hayek: "Happiness is exhausting"

Salma Hayek has revealed that motherhood has left her constantly tired.

The 44-year-old actress, who raises 3-year-old daughter Valentina with her husband Francois-Henri Pinault, admitted that juggling her family life with her career is a struggle.

Hayek, who recently finished shooting new comedy Here Comes the Boom, told USA Today: "[Motherhood] is all-consuming. And it's not temporary.

"I went out with my husband and my agent last night. They were making fun of me because I'm all the time, 24/7, 'Oh, I'm so tired'. They were laughing. I was laughing, too, but inside I wanted to cry because I'm so tired. I'm so happy. Happiness is exhausting."

Hayek has also created a new beauty, hair and skincare line called Nuance, and confessed that she didn't anticipate how much work the project would involve.

"If I had known how much work it was going to be, I wouldn't have done it. I'm incapable of letting someone else take over," she confessed. "I'm micromanaging."

Hayek's husband Pinault was recently confirmed as the father of supermodel Linda Evangelista's son.
