Before we find out who hits the high note a la mode at the 2012 Grammy Awards on Sunday, Breaking Celebrity News is bringing you on a walk down red carpet memory lane with all the rocking and shocking fashions of years past!

From wardrobe winners to sinners, check out all of the best, worst & wackiest fashions in the history of the music awards show in this special fashion flashback photo feature.

At last year's show, Miley Cyrus dazzled in Roberto Cavalli tiger stripes, while Katy Perry showed off her angelic spirit pairing her custom Giorgio Armani gown with a pair of wings!

In 2000, Jennifer Lopez stepped onto the red carpet of the 42nd Annual Grammy Awards with then boyfriend Puff Daddy, in a look that went on to become one of the most iconic dresses of all times. The Latina singer was dressed to shock in her dramatically low-cut and sheer Versace gown, which barely covered her [expletive]. That same year, Britney Spears wore one of her glammest looks ever, channeling Old Hollywood in a white hot tank dress.
