Geri HalliwellGeri HalliwellWe're actually blushing for Geri Halliwell.

It's surprising her face isn't as red as her frock.

But although we're cringing for Ginger Spice, we can't help guffawing too.

Imagine the scene - you've been getting ready all evening, dressing up in a sexy-senorita-stylee with tousled hair, red ruffles, and a pair of gorgeous heels to hit the red carpet...

Only to arrive at the Children's Baftas and experience a wardrobe malfunction of butt-puckeringly embarrassing proportions.

While posing for the paps, a gust of winter wind lifted the ruffle on her skirt and exposed Geri's derrière for all to see.

Oh, the mortification. Tee hee.

Check out Geri's buttock display, and a whole host of others in our gallery of rump-flashing celebs, below.
