Actress Penelope Cruz has revealed how she gets by on less than three hours sleep a night since she became a mum.

The 39-year-old and her fellow Oscar-winning husband Javier Bardem married in 2010 and now have two children: Leonard, 21 months, and Luna, born five months ago on the same day as Prince George.

But in an interview with the Mirror, Penelope revealed she now gets by on 'not even three' hours of sleep a night, but says the happiness she gets from being a mum makes it all worthwhile.

She said: "I don't mind. It fills you so much it doesn't matter that you're always exhausted. It gives you so much happiness. You want to enjoy every second."

But she revealed that since becoming a mum she has been gripped by fear.

She said: "I have so many fears. I have become an expert at hiding them but I am so full of them. I'm not giving you examples because they are all so crazy.

"Everybody thinks I'm so centred and relaxed but it's so opposite to what goes on inside me. But I've been working on it all my life, so it gets better."

Penelope and Javier, 44, both Spanish, met for the first time while filming the cult film hit Jamon Jamon when she was only 18.

She has worked virtually non-stop for 20 years but has now made some changes.

Even before she became a mother she had decided to cut back on her movies and the number of hours she worked.

The actress, who stars in the movie The Counsellor alongside Cameron Diaz and Brad Pitt, said: "I was always on a movie set so I was always another character and I was feeling very empty.

"I wasn't enjoying the work so much... I was going from set to set. I was never in my house and I didn't have a life.

"I changed that about six years ago because it wasn't making me very happy. You need to have time for your own life and as a mother that changes even more.

"Family is the most important thing for me... and if you have children you want to raise them yourself."
