2011 ACM Awards: Carrie Underwood performs with Steven Tyler 'Walk This Way'
"American Idol" met "American Country Music" Sunday night when country music's elite gathered in Las Vegas to honor their own at the the 46th Annual Academy of Country Music Awards.
One of the highlights of the two-hour ceremony was a duet between country music's "it" girl Carrie Underwood and "American Idol" judge and Aerosmith frontman Steven Tyler.
Carrie first appeared alone for Undo It before Steven Tyler joined her in the second half of the song. The two "American Idol" stars then rocked it out with a cover of Aerosmith's Walk This Way where they staged a kiss on the words "a little kiss like this".
