Miley Cyrus took to the stage at Las Vegas' iHeartRadio Music Festival for the first time since breaking up with ex-fiance Liam Hemsworth over the weekend.

And that's not the only thing Cyrus let hang-out... her skimpy lingerie-inspired getup also gave the audience a good look of what appeared to be one painful camel toe! Read on for more deets.

Cyrus' raunchy performance at the iHeartRadio Music Fest on September 21 included the "We Can't Stop" beauty twerking alonside dancing, dressed-up dwarves. Check it out:

And here's a (rather disturbing) close-up of Cyrus' form-fitting outfit. Looks sort of painful, doesn't it? Photos obtained by MediaTakeOut.com.

Despite another one of Cyrus' skimpy ensembles showing off a little TOO much skin, things took a turn for the serious with her rendition of "Wrecking Ball." Check out the tearful, heart-wrenching performance here:

The song is clearly about losing the love of your life - in Cyrus' case, Hemsworth. So no wonder why she got so emotional, considering the couple broke things off earlier this month, and Hemsworth's apparently already moved on with Eiza Gonzalez.
