Teen sensations Miley Cyrus and Taylor Swift reveal while On-Air with Ryan Seacrest their special Grammy surprise.

Miley and Taylor will be singing a duet at the Grammy Awards! Taylor, 19, and Miley, 16, will be performing Swift's song, "15."

"It’s a song I wrote about my freshman year of high school. I wrote it about all you think you know when you're 15," Swift said. "I'm just really glad I was able to put it into words all the things that happened that year."

"I was on tour when I turned 15," Cyrus said. "The lyrics are really inspiring. …This song is pretty perfect for the Grammys."

How did the duet come about? "We all kind of came to the consensus that 'Wouldn't it be cool if Miley was up there and we were singing together,'" Swift said.

The 51st Annual Grammy Awards will be broadcast live from The Staples Center in Los Angeles, on Sunday, Feb. 8 at 8 p.m. on CBS.
