Cameron DiazCameron Diaz's doubleUh-oh. Is Showbiz Sherlock playing mind games on us?

Because something ain't quite right with this snap of Cameron Diaz.

She's looking just a tad bit robotic round the edges.

And there's something almost maniacal about the glint in her eyes.

If you're a sharper tool than us, you will of course have realised that this ain't a pic of Cameron at all.

Rather it's a waxy double of the sun-kissed actress.

Yup, Cameron has reached the stage where she's just so darn famous she's got an imitation...

As has her Charlie's Angels pal Drew Barrymore.

The two figurines were unveiled side-by-side in the make-up area of London's Madame Tussauds.

But if you'd rather view them from the safety of your desk, go see the twosome in all their moulded magnificence in our gallery of waxwork stars.
