3. What's Sara's recent big news?
She's been named as the third celebrity judge of NBC's "The Sing-Off," alongside Ben Folds and Boyz II Men's Shawn Stockman. She's replacing former Pussycat Girl Nicole Scherzinger. I'm guessing if you have a ticket to tonight's show and that's exciting to you, this news is also important.
