Jennifer AnistonIf a star fancies an image change, they needn't dye their hair or have a boob job.

There's a quicker way - posing for a mag cover.

Women can become men, men can become robots, guitars can hang naked with Christina Aguilera...

The possibilities are endless.

Yet, the advantages don't end there. Oh no, no, no (Winston-the-nodding-dog voice).

You can get the rumour mill in full motion with a mummy-and-daddy photo shoot (yes, you, Brad and Ange).

But don't go thinking that a certain hard-done-by person doesn't have mags at her disposal either. Step forward Jennifer Aniston sans top...

So we think you get the gist that mag covers are an endless source of experimentation for celebs and entertainment for the rest of us.

So without further delay, strike a pose and look at some of our mag cover faves.
