It has only been four months since singer/songwriter Adele underwent vocal chord surgery, and with her upcoming Grammy performance on the horizon, many fans have worried that her voice may need more time to recover.

Adele helped to dispel some of this speculation in a recent interview with Anderson Cooper, where she gave her first public performance since she went under the knife.

Adele has been nominated in six categories in the 2011 Grammys including Record of the Year, Song of the Year, and Best Pop Vocal Album of the Year. She has also been dominating the billboard charts all year, with four tracks from her album '21' peaking at the #1 spot.

While the rest of the world worried about whether or not her vocal chord surgery would have affected her singing abilities, Adele doesn't seem to be the least bit worried. She actually seems pretty confident in the '60 Minutes' interview.

During the lovely a capella performance of her hit song 'Rolling in the Deep,' Adele's voice seemed to be just as strong and powerful as ever. Honestly, you wouldn't even know that she just had surgery. Still, if anyone doubts that she hasn't fully recovered, we're sure she'll help to put those lingering worriers mind's at ease on February 12th.

You can catch the rest of Adele's '60 Minutes' interview on February 12th at 7pm EST on CBS right before the Grammys.
