Kelly Brook - and someone not Billy Zane...Kelly Brook has embarked on a gruelling diet and fitness regime with the help of her boyfriend, British rugby player Danny Cipriani. © Solarpix / PR PhotosThe 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."
