Carrie took over the stage in a super cute rock n’ roll costume with a microphone with a big tail to perform her hit “Undo It”, when the Idol judge arrived to give her country swagger a new flavor. The two ended up performing Aerosmith’s classic “Walk This Way” to a crowd totally on fire.

Carrie and Steven even staged a “kiss” on stage with the words “a little kiss like this”. Steven loves country… hot country women! The kiss was not real… there was no lip contact at all because Carrie is happily married to Mike Fisher.

Loved it! Incredible. Carrie is an amazing performer. Steven Tyler still got it. Perfect duet. We want more! Singer Rihanna also performed her song “California King Bed” with Sugarland’s Jennifer Nettles during the awards ceremony.
