LL Cool J will return for a fifth year in a row to host "The GRAMMY Nominations Concert Live!! - Countdown To Music's Biggest Night" -- and this year, he'll have a fellow Grammy winner as his co-host. Taylor Swift has signed on to help her rap icon friend emcee the one-hour television special, set to air Dec. 5 at 10:00 PM ET on CBS. Taylor also co-hosted with LL back in 2008.

For the first time ever, the show will broadcast live from Nashville, at downtown Music City's Bridgestone Arena -- the same venue where this week's CMA Awards will take place. Luke Bryan and Maroon 5 will perform on the show, with more artists expected to be added to that lineup in the coming weeks. In addition to the star-studded performances, the show will reveal nominations in several Grammy categories.

After the live TV broadcast, fans at Bridgestone Arena will be treated to a concert by an artist who has yet to be announced. Tickets are on sale now via Ticketmaster.

The 55th annual Grammy Awards are set for Feb. 10 in Los Angeles.
