Abdominal anomaly ... shirtless photos of Tom Cruise fuel liposuction speculation.

Abdominal anomaly ... shirtless photos of Tom Cruise fuel liposuction speculation.

Summer's just around the corner, which is always the time to start worrying about appearances.

Like, what is going on with Tom Cruise's stomach?

Shots showing the Mission Impossible zipping down a flying fox in Prague (shirtless) have belatedly come 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,'' said 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. But could the medically diagnosed belly frown be a sign of a different kind of tummy trouble? After all, ''Tom would love to have a baby to coincide with the premiere of MI4,'' a source explains one page earlier.

As long as that remains a medical mission impossible, and Katie Holmes is reluctant to become pregnant, marriage tensions (and frowning bellies) abound.

Indeed, a non-smile can be a vital non-verbal cue. If only someone had taken a long look into the forlorn muzzle of Jennifer Aniston's corgi-terrier cross Norman and noticed the little white dog was battling the big black one: depression.

Instead, NW reports the 15-year-old pampered pooch boarded a plane with Aniston to Atlanta, disappeared momentarily from her movie set and was subsequently diagnosed as ''suicidally depressed''.

Considering the film was called Wanderlust, there's an outside chance it was just sniffing out Aniston's motivation.

Elsewhere, Heidi Montag continues her post-surgery arc of personal development, conceding to Who that ''vanity'' was the reason for her 10 plastic surgery procedures in a single day.

''It is my own insecurities and I should have dealt with it inside,'' she says. Such is her new aversion to surgery that Montag is not prepared to have her ''little bit too-big breasts'' reduced. ''I don't even want to get lip injections,'' she says.

And nor would you, after reading the harrowing account of Lisa Rinna. The Melrose Place actress had 30 per cent of her lips removed after silicone seeped through and damaged tissue. ''Talking is easier,'' Rinna said, through her untrout pout.
