So You Think You Can Dance
9 pm/ET Fox
After tonight's results, the show will be down to 12 contestants, and these dozen dancers might want to watch and learn from the featured performer, Kelly Clarkson. Clarkson won the first season of American Idol, so she obviously knows how to survive on a reality show, and tonight she sings "I Do Not Hook Up" from her fourth album, All I Ever Wanted. Also, professional dancers Desmond Richardson and Patricia Hachey perform a pas de deux.
