LL Cool J is hosting the Grammy Awards Nominations Concert for the fifth straight year, but when members of the Recording Academy found out that Taylor Swift was also available, they couldn't pass up the opportunity to invite the pop-country superstar to co-host.

This year's show, titled 'The Grammy Nominations Concert Live!! — Countdown to Music's Biggest Night,' airs live from Nashville on CBS at 10PM ET on Dec. 5. Swift has come a long way since she last co-hosted the special in 2008. She has won six Grammys, and she was the youngest artist ever to win Album of the Year when 'Fearless' claimed the award in 2010.

Hopefully Taylor has been practicing her "I'm shocked!" award show expression, because she's likely to be one of the stars earning multiple nominations for the 2013 Grammys. Though her new album 'Red' was released after the Grammy cutoff date for this year, its lead single 'We Are Never Ever Getting Back Together' is eligible, as is her duet 'Safe & Sound' with the Civil Wars.

In addition to naming the 2013 Grammy nominees in every major category, the nominations concert will feature live performances by Maroon 5, country singer Luke Bryan, and others to come.
