Lady Antebellum are one of the biggest names in country music right now, they've had hits on country, hot a/c, a/c and top 40 charts and now they're going to be a part of one of the biggest shows on TV right now, American Idol.

They'll take over the American Idol stage next Thursday during the results show but they won't be the only ones on the stage...judge Jennifer Lopez along with special guest Pitbull will be performing too.  Once these performances are done American Idol will have it's top 4 for season 11.
