Before stars hit the red carpet of the 2012 Teen Choice Awards on Sunday, Breaking Celebrity News is bringing you a fashion flashback of all the best, worst & wackiest fashions the annual awards show over the years.

There is always an excess of sexy at the show, as many starlets gear up in racy designer dresses. In 2009, Hayden Panettiere was pretty in pink Zac Posen, while Ashley Greene showed off her hot bod in a Dolce & Gabbana corseted ensemble.

Before Britney Spears had us humming Oops…She Did it Again with all her style sins, the pop tartlet left us panting for air when she hit the red carpet in truly scintillating style.

Fergie’s farmgirl getup was one of the several fashion faux pas committed by our favorite stars at the annual teen-oriented show. Remember when Jennifer Lopez wore sweats in 2001 to collect her Choice Female Hottie?  Or how about when Beyonce and the Destiny’s Child babes hit the red carpet that same year, wearing matching neon yellow doily duds?
