Leona's Weight Secret

Leona Lewis looks much more slimLately she's been looking incredibly slim.

And now Leona Lewis has revealed the secret to her new trim shape.

But we're not saying it's easy...

The singer says it's all down to a strict month-long detox.

Speaking to this week’s Closer magazine, the former winner says: "I went on a detox at the end of summer last year and basically ate vegetables and nothing processed.

"I didn't drink anything but water for a month. I usually drink lots of water anyway, so it wasn't a crazy, dramatic change to my lifestyle, but I just really wanted to try it and see how I felt.

"And after being in the studio a while, I started doing shows and getting more active.

"I only did the detox for a little while, but it must have kick-started something in me because everyone keeps saying: 'Wow, you’ve lost weight.’ and I’m like: ‘Cool.’”

The 24-year-old has dropped two dress sizes to a 10, but insists she's never felt under pressure from the music industry to lose weight.

"No one’s ever said: ‘You need to work out more.' I put pressure on myself to stay healthy and I do want to look good, but I like to eat and I don’t like to starve myself." Leona before her strict detox

This is a girl clearly after our own hearts as she admits she finds the gym "boring" and says the hardest thing was giving up the sweet stuff.

"I love chocolate, it was so hard for me. But I thought, ‘It’s only a few weeks. You can have it, but it’ll make you fat! So do you want that or to be healthy and feel great?’”

And, despite spending a great deal of last year in LA working on her new album, she refuses to cave to the super-slender Californian stereotype.

She adds: "There’s a lot of skinniness out there, but it’s really outdoorsy and I love that. It’s always sunny and I loved going on horse trails and hiking in the canyons.

"At first, I didn't like LA – it's so vast and you have to drive everywhere. Everyone has this perception that I’m over there a lot, but it’s just for work. My life is in London."

Leona's help For Haiti

Leona Lewis is the latest star to sign up to Simon Cowell's Haiti charity single.

It's believed the song will be a cover of REM's classic hit Everybody Hurts, which will benefit from an all-star line-up.

Along with Leona, Cheryl Cole, Michael Buble, JLS and RoSimon Cowell Simon Cowell d Stewart have all agreed to contribute.

Take That, Robbie Williams, Coldplay, Will Young, X Factor 's Joe McElderry, N-Dubz and Sir Paul McCartney are also said to be in talks to be part of the Live-Aid style single.

Prime Minister Gordon Brown said: "I have already talked to Simon Cowell and I said there would be an exemption from VAT for a charity single.

"The agony and anguish for the people that we are seeing on our television screens is something that British people want to respond to.

"Simon Cowell can make a huge amount of money to help the people of Haiti."

REM have agreed to waive any royalty rights to the song so the charity single can raise the maximum amount of cash for the striken country of Haiti.

Leona Lewis in a drama

Leona Lewis is recovering in LA after falling from her horse.

The singer needed hospital treatment after the accident on Wednesday 30th December.

It's believed the X Factor star was thrown from the animal after it began galloping too fast.

The 24-year-old is now on crutches to start the new year.

A source told The Sun: "Leona was riding the day before New Year's Eve and fell off when the horse started galloping too fast.

"She went to Accident And Emergency. It was pretty scary. She had quite a tumble.

"But it hasn't put her off riding. She's fine and will be back on her horse soon."

She certainly didn't let the incident spoil her celebrations - she was spotted partying at singer Robin Thicke's NYE bash in Las Vegas's Bellagio Hotel.
