Taylor Swift Ready For CMT Music Awards Wednesday Night!

Nelly, Hunter Hayes, Carrie Underwood and more will perform on the 8 p.m. broadcast tomorrow on CMT.

The 2013 CMT Music Awards are just around the corner and the roster of superstar performers and presenters just keeps getting bigger.

The show will air live from Nashville's Bridgestone Arena on Wednesday night at 8 p.m. ET/PT on CMT with performances by Taylor Swift, Hunter Hayes and Carrie Underwood, as well as just added collaborations featuring Lenny Kravitz (who will team up with the night's co-host, Jason Aldean) and "Country Grammar" rapper Nelly, with breakout jam-of-the-summer act Florida Georgia Line for a version of their crossover hit, "Cruise."

"A lot of energy, we're going to have a lot of fun," long-time country music fan Nelly promised of his hook-up with FGL on the remix of the song. "It's the guys' first year of making the rounds, so to speak, so I know they're real excited. I'm real excited. It's my first time performing at [a] country music awards [show] ... so, we've got a lot of pumped-up anxiety."
