Kelly Clarkson is indulging fan requests on her current tour, playing whatever covers her fans request in advance and want to hear. At her Austin, Texas stop, Clarkson went country, something she's been hinting at doing with her own music. She covered Pistol Annies' 'Hell on Heels,' musing that the song was requested by multiple people -- and likely because she was in Texas. Texans love their Miranda Lambert, who's one third of the Pistol Annies. Clarkson is also a close friend of Lambert and a native Texan, like her blond pal, so it was the perfect cover song.
