Over the years, American Idol has attracted many top stars to its finales, so why should The Voice be any different? The NBC show has just announced that the May 8 finale will include performances from Justin Bieber, Flo Rida and Lady Antebellum.

Justin, who appeared on The Voice a few weeks ago to premiere a snippet of his video for "Boyfriend," will return to perform that song on TV for the first time. Flo Rida, meanwhile, will perform a medley of his hits, including his latest, "Wild One." As for Lady Antebellum, they'll perform "Wanted You More," a track from their current album Own the Night.

During the two-hour finale, the winner of The Voice season two will be crowned. You may recall that last year, the winner was Javier Colon, from Team Adam. Actually, we're sure you recall, since Adam Levine never stops reminding his fellow judges of that fact.
