When the two-hour season finale of Fox’s "So You Think You Can Dance" airs on Dec. 16 at 8 p.m., two music stars will be on hand to lend their talents.
Jennifer Lopez will be singing her latest single, "Louboutins" and Mary J. Blige is slated to sing "I Am." The grand finale will feature additional performances by Adam Lambert, Leona Lewis and the Groovaloos.
