It's the No. 1 song of Summer and we've seen everyone from President Obama to the US Olympic Swim Team to Katy Perry cover it and now Kelly Clarkson takes on Carly Rae Jepsen's Call Me Maybe! The American Idol alum performed the song at her concert at the Mixtape Festival in Hershey, Penn over the weekend. Done during what Kelly calls her favorite part of the show, when she sings a song requested by a fan.

"Oh my gosh, I love that song," Kelly said of Call Me Maybe. Adding, "But it kind of confuses me. Does it confuse anyone else? 'Before you came into my life I missed you so bad.' Who did you miss? Because you didn't know them?"

What did you think of Kelly's cover?
