Jessie J wows the red carpet with the most revealing outfit of the night so far!

We love Jessie J, especially when she turns up and makes an entire red carpet gasp - which is exactly what she's done tonight at the Brits 2012.

The Domino singer had every photographer screaming her name as she walked down the carpet in a floor-length, sheer-red number - we're guessing her male fans were delighted by the view of her bottom!

Jessie, who won the Critics Choice Brit Award last year, is bound to have delighted her male fans by choosing a dress that shows off not only her toned-figure... but also her bottom, which is clearly visible through the lace!
