"Their entire upcoming tour sold out in less than a day. BIG TIME RUSH are the newest pop superstars! They're making their Ellen show debut to talk to Ellen about their Disney series, "Big Time Rush," and to perform their hit, "Music Sounds Better with You," from their CD, "Elevate."
Plus, Amy is going undercover for a hilarious hidden camera adventure you won't want to miss!"
Of course by Disney they mean Nickelodeon. We can't wait to see BTR perform on Ellen!
