One Direction 'X Factor USA': Top 12 Contestants Take On 'Live While We're Young' (VIDEO)

It's going to be a big week on "X Factor USA." After months of auditions and many rounds of eliminations, thousands of hopeful contestants have finally been whittled down to the season's top 12 finalists -- and this evening, audience members can vote for their favorites. To get pumped up for this week's live shows, "X Factor" put together this super cute, high-energy lip dub to One Direction's hit single "Live While We're Young."

And that's not all: One Direction themselves will be stopping by "X Factor USA" on Thursday to perform "Live While We're Young" and "Little Things" on the live results show. (!)

“It’ll be the first time we’ve performed in front of ‘Uncle Si’ since we were on UK X Factor," said Niall. "So, hopefully we make him proud.”
