TOP 20 FINALISTS - 10 STAGE AND 10 STREET DANCERS - REVEALED ON "SO YOU THINK YOU CAN DANCE"; BUT ONE MUST LEAVE THE COMPETITION

FIND OUT WHO IS THE REPLACEMENT WHEN THE FINALISTS COMPETE ON FIRST LIVE PERFORMANCE SHOW MONDAY, JULY 13, ON FOX

JASON DERULO ALSO TO PERFORM AND CAT DEELEY TO INTERVIEW FIRST LADY MICHELLE OBAMA

Tonight, after thousands of auditions by the best dancers around the nation, and the grueling, week-long callbacks round, the judges - Paula Abdul, Jason Derulo and Nigel Lythgoe - announced the Top 10 stage finalists and Top 10 street finalists on Season 12 of SO YOU THINK YOU CAN DANCE.

This season's Top 20 finalists are: Stage: Gaby Diaz, Darion Flores, Kate Harpootlian, Edson Juarez, Alexia Meyer, Marissa Milele, Jim Nowakowski, Moises Parra, Hailee Payne and Derek Piquette. Street: Megan "Megz" Alfonso, Yorelis Apolinario, Ariana Crowder, Eddie "Neptune" Eskridge, Lily Frias, Virgil Gadson, Burim "B1" Jusufi, Alain "Hurrikane" Lauture, Jessica Rabone and Jana "Jaja" Vankova. However, at the end of the show, it was revealed that one of the finalists will not be able to accept his/her spot due to an injury, and a new dancer will be named during next week's LIVE show.

The LIVE competition kicks off Monday, July 13 (8:00-10:00 PM ET live/PT tape-delayed), when the replacement dancer is revealed and the Top 20 perform for the first time for America's vote. Also, Jason Derulo will perform a world premiere medley of new singles "Cheyenne" and "Get Ugly" and Cat Deeley interviews First Lady Michelle Obama. Beginning the following week one dancer from team stage and one dancer from team street will be eliminated each week leading up to the season finale. Who will win... a dancer from the stage or the street?
