Miley Cyrus may find herself going head-to-head in a dance off with Will Smith at Sunday's Teen Choice Awards.

Miley and her best buddy Mandy Jiroux have been engaged in a months-long YouTube dance-off with Step Up 2 actor-dancer Adam Sevani, and rumours are that Sunday marks the final round of the fancy footwork battle.

In an interview with E Onlines Mark Malkin, Sevani reveals... "Will Smith is so cool, I did the Kids Choice Awards with him, and he was just so cool.

I wanted to use him for our (Teen Choice) performance, but I don't know if he's gonna be here."

Even without Mr Smith, Sevani promises that the five-minute dance-off will make Teen Choice history!
