Taylor Swift's Red Hot Night at the 2012 iHeartRadio Music Festival

Bringing her country charm to one of music’s biggest events, Taylor Swift was on hand to take the stage at this year’s 2012 iHeartRadio Music Festival in Las Vegas on Saturday night (September 22).

Swapping out of a bright red dress and into her sparkly custom stage frock, the "Fearless” songstress confidently belted out her biggest tracks at the MGM Grand Garden Arena venue.

Prior to offering up her energizing performance, Miss Swift roamed the backstage area while mingling with fellow country crooner Brad Paisley and concert closer, Pitbull.

The 22-year-old also took a moment to chat with iHeartRadio's Elvis Duran and Ellen K about her fear of slot machines, love of a screaming crowd and how she likes to relax at home. For Taylor's complete interview, check out the player below!
