Natalia Vodianova has split from her husband Justin Portman.

The Russian supermodel and the British billionaire - who have three children, Lucas, nine, Neva, five and three-year-old Viktor, together and were married for nine years - decided to separate "a while ago" but have only just confirmed the break-up.

The 29-year-old beauty told ES magazine: "It's really sad. It has been a while. We didn't want to talk about it. We still don't. Our children are very much aware of it. It's OK.

"We're still in a very sensitive position right now, and trying to do things as amicably as possible, so I wouldn't want to talk about it at all.

"I don't think I ever will want to because it's strictly between my husband and me."

While she is no longer in her marriage, Natalia - who has a new man - loves being a mother and has previously said she is "addicted" to pregnancy as she loved what it did to her body.

She said: "I love it. I'm addicted to it.

"In my first pregnancy my body changed greatly. I became a woman, my hips opened, I developed breasts and I lose lots of baby weight from my arms and face.

"Before Lucas, I looked about 14, which restricted the kind of work I could get. Then, suddenly, I became good material for more sophisticated work. And it was all thanks to my son and my pregnancy."
