Kelly Brook's gruelling diet

Kelly Brook has embarked on a gruelling diet and fitness regime with the help of her boyfriend, British rugby player Danny Cipriani.

The 29-year-old model is said to be so impressed by Danny's toned body she has asked him to come up with a plan to help her shape up after a calorific Christmas.

A source said: "Danny has an incredible physique and works really hard to maintain it. Watching him go off to the gym every day, Kelly has been inspired to follow suit and get fit.

"She also loves how much food he can eat on his regime, and thinks if a bit of hard work on the treadmill means she can eat what she likes then it's worth it."

Danny has reportedly made an intensive workout plan for Kelly, which includes power squats, bench presses and a variety of other exercises the 21-year-old sportsman uses in his training sessions with his rugby team the London Wasps.

The source added: "Danny thinks Kelly is beautiful as she is but agreed to devise a training programme for here. He has used one similar to that given to the Wasps boys, but obviously she is lifting far lighter weights. As well as sprint and interval training, Danny suggested some serious weightlifting work."

Kelly has also started asking Danny for tips on what she should eat to help her slim down.

The source told Britain's Daily Mirror newspaper: "Kelly is eating more in line with Danny now - egg whites and lean, skinless chicken for breakfast and more protein. Any weight she put on over Christmas will go in no time.

"Kelly is really excited about her new lifestyle."

British model and actress Kelly Brook has reunited with Billy Zane.

The 28-year-old star is back with Billy, 42, after breaking off their engagement last month.

Wooed.......chocolates and roses

The ‘Titanic’ actor flew in from South Africa to meet with Kelly in London.

After wooing her with chocolates and roses, the couple spent the night together at a luxury hotel.

Kelly - who broke off a holiday in Newquay, South West England, to see Billy - has since agreed to give their four-year relationship another chance.

Lucky guy. Make no mistake.

Although there was no sign of her £35,000 engagement ring, Kelly looked happy as the couple enjoyed dinner at a Thai restaurant.

One source told Britain’s The Sun newspaper: “Billy looked like the cat who got the cream. But she was teasing him - it looked like she was keeping him on his toes.”

Speaking about the pair’s relationship, Kelly previously said: “It's never me that is the first one to make up. We're both romantics so there's lots of magic. I've met someone I want to do everything with. He's my best friend really. I've never had that before.”

The couple were originally set to marry last year but had to postpone the nuptials following the death of Kelly’s father.
