Ryan reminds us Adam Lambert will mentor next week. Katie Stevens is shocked and says she didn't know. She's either really surprised or a good actress. Ryan doesn't specify on next week's theme, however.
Time for a Jason Derulo performance. He sings "In My Head" and I really love it. This is a good party hit. I love the slow motion black and white cam, too. Remember, "Idol" judge Kara DioGuardi had a hand in discovering Jason.
He's definitely one of the better guest stars of the season. Even Simon has nice things to say about his performance.
