Zachary Levi Tweeted this video of Yvonne Strahovski dancing to Justin Bieber’s Baby and said, “Nerds and Nerdettes, I present to you…(drumroll please)…Yvonne Bieber. Don’t hate, and don’t get a crush!” Looking at her moves, I think Jeffster might have some competition from Sarah Walker this season. Seriously how much fun would it be if the Buy More had a Talent Show this season and Sarah entered with those moves. Or maybe Chuck and her will have to go undercover as a hip hop band…? Whatever they do I can’t wait for Chuck to come back on NBC on September 20th!
