Now, via Twitter, he's finally called himself out on his own obsession with these tweets of the week: "Good night or good morning to everyone. Ps I am addicted to rise protein bars the almond honey one." Follow-up tweet: "And kittens." There you have it, folks, Mr. Nasty has a soft spot for purrrttyyyy little kitties!
Feline fun aside, this week had more than its fair share of notable tweets from our own celebrity judges and hosts about Britney Spears' birthday and Mario Lopez's wedding, as well as from others about this week's Top 6 performances and results. And, One Direction's Harry Styles seems to have a new favorite, Ke$ha tweets a backstage shot, and Kris Jenner and Britney's dog have a cute exchange!
