Bill Nye the Science Guy, Valerie Harper, Leah Remini, and Noel Kahn: is this best Dancing with the Stars cast to date? We'll sure find out when Season 17 of the wildly popular reality competition kicks off tonight.

Well, it's time to find out which has been all star will win the coveted craft-store disco ball.

In case you've missed your daily dose of washed up D-list celebs attempting to dance, Dancing with the Stars is back on.

It's that time already! Tonight one of the three finalists can call the ugliest trophy ever created -- ahem, the Mirror Ball trophy -- their own. (Seriously, who okayed the design for this?! It looks like an oversized, glittery microphone/disco ball hybrid that's super awkward to carry. And Tom Bergeron basically said it's cheap.) Hey, at least after this they can relax and eat all the food they want on Thursday!

Will Ricki Lake put other stars to shame with her Hairspray moves? Is the world going to implode when Cher shows up to support her son? Will Kristin Cavallari and her partner, Mark Ballas, hook up? How long will Nancy Grace last? Only time will tell on this season of Dancing with the Stars, but we hope the answers to these questions are: Yes, Yes, Gross and Until Tomorrow.
