Carrie Underwood, Steven Tyler Sing 'Walk This Way' (Video)

The "American Idol" winner and current "Idol" judge perform the 1970s hit song with his band, Aerosmith, at the Academy of Country Music Awards.

Carrie Underwood teamed up with Steven Tyler and Aerosmith to sing the group's late-1970s hit "Walk This Way" at the Academy of Country Music Awards show Sunday night.

The song, which Aerosmith remade a decade later with Run D.M.C., got a rousing reception as Tyler and Underwood belted it out in Las Vegas.

Incidentally, Tyler serves as a judge on the current season of American Idol, which Underwood won in Season 4.

The ACM Awards air live on CBS from the MGM Grand and Mandalay Bay.
