It's here! Kellie Rasberry has unleashed "Phat Mix Tape," a song that is all but guaranteed to rocket to the top of the Billboard charts.

With lyrics like "You got a big gut/You got a bigger butt/Say what, what/I got a phat mix tape" it's safe to say Kellie has a smash hit on her hands.

The song, written for the Kidd Kraddick show's Hot Hook Challenge, has a beat that makes it impossible to not want to throw on yoga pants and hit the gym hard after hearing.

You can listen to J-Si, Big Al and Jenna's songs for the Hot Hook Challenge at the Kidd Kraddick show's website. But before you do that, watch Kellie's "Phat Mix Tape" video below!
