Has Tom Cruise gone under the knife?

Shirtless Tom have sparked speculations that the he has gone under the knife.

Sydney: Shots that show Tom Cruise zipping down a flying fox in Prague (shirtless) have sparked speculations that the actor has gone under the knife.

The shots belatedly came to the attention of Woman`s Day via the gossip sites. The mag sought to advance the hypothesis that the action star has sought a doctor to help him surgically suck it in. ``This is all abnormal,`` the Sydney Morning Herald quoted a Sydney cosmetic surgeon, Dr Michael Zacharia, in reference to odd horizontal markings across the 48-year-old`s paunch. ``His belly button also has the classic downwards smile of a lipo case.`` The mag concedes it is `also possible` that unusual muscle configuration is a result of vigorous training.
