PAULA ABDUL

Then: The choreographer turned pop star topped the charts in '91 with "Rush Rush" – remember its Rebel Without a Cause-inspired video, costarring Keanu Reeves? Her love life also made headlines, when she married and later divorced Brat Packer Emilio Estevez.

Now: The American Idol judge is straight up returning to her roots! Abdul unveiled "Dance Like There's No Tomorrow" – her first single in 15 years – at the Super Bowl. The track will appear on fellow Idol judge Randy Jackson's compilation, Randy Jackson's Music Club, Vol 1. No word yet on MC Skat Kat's cooperation.
