Will the new Beatles or 5th Harmony make it to the final?
The Top Four acts tried to showcase their best stuff on today's X Factor semifinals.
"This is crazy!" said co-host Khloe Kardashian Odom. "I can't believe the finals are next week!" Only three acts will advance. There will be no sing-off and no judges' decision this week, announced her co-host Mario Lopez. It's all up to viewer voting.
