Kesha brought her signature brand of party pop to the 2013 iHeartRadio Music Festival -- and some special guests, too. The 'Crazy Kids' singer was joined onstage by none other than rock legend Joan Jett ... and by Kesha's own best friend, Jack Daniels.

The iHeartRadio Music Festival commandeered Sin City this weekend. In case you missed it and couldn't make it, we've recapped the event in the form of live photos of Miley, Katy, JT and more. Go ahead, check the photo recap out. These pics will make you feel like you were there.

Miley Cyrus (or Miley "Cryrus," if you want to get pun-happy) gave the first-ever live performance of her new smash 'Wrecking Ball' at the iHeart Radio Festival yesterday (Sept. 21).
