Rascal Flatts have added extra star power to their TV concert special, 'Nothing Like This Presented by JC Penney.' The March 12 broadcast will include special appearances by Justin Bieber and Natasha Bedingfield.

The hour-long concert special will feature a never-before-seen clip of the Flatts' collaboration with Justin on the new song, 'That Should Be Me,' from the teen pop star's latest CD, as well as behind-the-scenes footage of the making of the video. (The photo above was taken on the video's set and tweeted by Justin.) Natasha, who appears on Rascal Flatt's latest CD, 'Nothing Like This,' surprised a packed crowd during the group's concert in St. Paul, Minnesota, in January, with that footage also included in the TV special.

Incidentally, it was during the taping of the video that Gary LeVox famously cut off a lock of Justin's hair to donate to charity. The bidding war just ended, and earned more than $40,000 on eBay, with the money going to the animal rescue foundation The Gentle Barn.

Rascal Flatts will be in Oklahoma City the night the show airs, performing as part of their Nothing Like This tour, which runs through October. See their schedule here.

'Nothing Like This Presented by JC Penney' airs March 12 at 8:00 PM ET on ABC.
