Kelly Clarkson Covers Janet Jackson's "If"

Kelly Clarkson sings her own rendition of Janet Jackson‘s hit song “If” at the PC Richard and Son theater in New York City’s TriBeCa neighborhood on Tuesday night (July 13).

The 27-year-old original American Idol performed a 16-song set, which also included a bluesy and soulful tribute to Patsy Cline‘s “Walkin’ After Midnight.” JustJared.com was lucky enough to attend the private concert and it was to die for. Kelly always changes up her classic songs and throws in some new ones. And the acoustics in the theater were awesome!!!

The event was sponsored by Z100 radio station and iHeartRadio, which has a Jonas Brothers concert coming up on Monday. Enter to win tickets here!

FYI: Kelly is wearing a cut up shirt of one of her music idols, David Bowie!
