It down to the quarter finals on NBC's America's Got Talent. 12 of the Top 48 performed, hoping for America's vote. Melissa Villasenor is a comedian who does impressions. She took on Drew Barrymore, Owen Wilson, Sharon Osbourne, Britney Spears and Michael Jackson. Check out the video and judge for yourself how close she came. I thought she nailed Michael and Britney. Find out who moves on to the next round tonight on NBC at 9.
