Paris Hilton happy to be a few pounds heavier

The 5' 8' socialite weighed just 105 pounds and wore a US size zero before meeting her man, and said even her mum Kathy had started to worry about her.

'I'd been to every incredible party in the world,' she said. 'But I was going out with my girlfriends and dancing, having a lot of coffee and Red Bull. Being on the go, I would just grab fast food or skip meals because I was busy. She (Kathy) would be like, 'You're way too skinny. It doesn't look good’, I said, 'Mom, everyone is skinny in Hollywood. It's just the way it is.' And she's like, 'No. It's not normal’.”

But she told People that as soon as she met former nightclub owner Waits last summer, she decided to take more care with her diet.

'He explained everything to me. Now I only eat organic foods when we're at home. He makes me watch documentaries on food, like Fast Food Nation, and he makes me aware of what things are good for your body because he's very into that,” she said.

But by December she sparked pregnancy rumours when her weight went up to 125lbs, although she has now settled on 115lbs.

'Even if I'm a few pounds overweight, people will be like, 'Oh, she's fat’,” said the World According to Paris star. 'And it's not fair that it's like that, but it is. I'm really happy with the weight I'm at. I feel like it's healthy and normal … I'm just making smart choices.'
