The cast for season 17 of Dancing with the Stars was announced this morning on Good Morning America. It will be an exciting and diverse match up competing for the Mirror Ball trophy again. Let's take a look at the dancer's we will be voting for this season.

Earlier this year, Valerie Harper was diagnosed with terminal brain cancer. But that won't stop the 74-year-old The Mary Tyler Moore Show star from having some fun. According to the Daily News, she claims that her brain scans are improving, so she will be teaming up with Tristan MacManus this season.

43-year-old Leah Remini from The King of Queens has lit up our television screens since she was 18 years old, playing roles on beloved sitcoms such as NYPD Blue, Friends and Saved by the Bell. She can now add DWTS to that list as she joins professional dancer Tony Dovolani in the fight for the Mirror Ball trophy.

27-year-old Amber Riley of Glee is the lucky contestant who drew Derek Hough for a partner. Hough is the only four-time winner in DWTS history.

Nicole “Snooki” Polizzi will try a different kind of reality show for a change. Hopefully the 25-year-old will leave any Jersey Shore drama at the door before she teams up with professional dancer Sasha Farber.

Actress Elizabeth Berkley Lauren gained fame through the show Saved by the Bell, and Val Chmerkovskiy plans to mentor the 41-year-old into the dancing spotlight as well.

Christina Milian can sing and she can act – but can she dance? We will soon find out. The 31-year-old partners up with two-time winner Mark Ballas.

Keyshawn Johnson joins the cast as the football player for the season. The 41-year-old ex-jet receiver pairs with Austrailian dancer Sharna Burgess. Johnson will have to dance his way to the top like his fellow NFL dancers Emmitt Smith, Donald Driver and Hines Ward.

The youngest contestant of the season is High School Musical star Corbin Bleu. Karina Smirnoff will work with Bleu to improve his dancing from the cheesy Disney dance numbers to more impressive performances.

Ozzy Osborne's 27-year-old son is following in his sister's footsteps, since Kelly was a finalist on the show a few seasons ago. Cheryl Burke will try to help Jack accomplish that feat. If nothing else, he'll bring some spunk to the show.

This is one situation that Brant Daugherty can't lie his way out of. The Pretty Little Liars star joins professional Peta Murgatroyd this season.

If all the dancers fail, at least we'll have a comedian. 56-year-old Bill Engvall will be trained by professional dancer Emma Slater, a rookie to the show.

He's not the only Bill joining the show. Bill Nye “The Science Guy,” 57, will try his chemistry on Tyne Stecklein, also a rookie this season.

The 17th season of “Dancing With the Stars” kicks off on Sept. 16 on ABC.

Just as Fox's So You Think You Can Dance only aired one night a week this season, ABC News reports that DWTS will also combine the performance and results shows into one two-hour program. For the first season ever, the show will only air every Monday night.

So who will it be - The 74-year old? The football player? The Science Guy? Get your early predictions in now. And tune into ABC on Monday, September 16 to catch DWTS's premiere of season 17.
