Miley Cyrus was in Las Vegas this past weekend to perform at the iHeartRadio music festival. During her performance she cried on stage while singing her new song "Wrecking Ball," which is supposedly about ex-fiance Liam Hemsworth.

Miley was all smiles, however, when she proved that she, too, keeps up with the Kardashians. The singer was wearing nothing but a mesh "cover-up," underwear and pasties, but that didn't seem to bother anyone in the Kardashian crew.

Kylie Jenner, Kourtney Kardashian, Khloe Kardashian and Kendall Jenner arrived at the festival in style as they took a private jet from Los Angeles to Las Vegas and posted lots of pics of their posh "ride."

Khloe Kardashian seems to be in good spirits, despite the fact that she and her husband Lamar Odom are reportedly living separate lives and with divorce rumors swirling around them.

We're glad to see Khloe smiling and we love that Miley is hanging with the Kardashian clan...who knows, maybe she even taught them how to twerk?
