Tom Cruise has reportedly put on a bit of a paunch and has the unenviable task of getting himself fit. He's done what any red-blooded male would do in his position - enlisted David Beckham as his personal trainer. A source said: "David has been round at Tom's house a lot. While Katie and Victoria have been swapping fashion tips on the phone, David has been advising Tom on diet. Tom has a private gym at his home and David has been working out with him. He also gave him diet advice. Tom has been sticking to 1,200 calories a day, mostly grilled chicken and fish with lots of vegetables, salads and fruit. David put together a work-out regime that included the treadmill, weight training and fencing lessons together." With those tight white onesies and all the arm flourishing? Manly. Seemingly the reason (like there had to be one) why Tom decided to get in shape is for his wife and kiddie... "Tom had been steadily gaining weight. He didn't notice it at first but then he developed quite a paunch. He hated it when pictures started appearing of him with a belly and love handles. He turned 46 this summer and he's got a 29-year-old wife and a young family so he wanted to get back in shape." That's their story and they're sticking to it.
