We've forgotten what Miley Cyrus looks like with proper clothes on.
The former Disney star sported not one but two barely-there outfits this weekend, but even these couldn't distract from her clearly fragile mental state.
Miley was performing at the iHeartRadio festival in Las Vegas on Saturday and chose white latex for the occasion.
In her cropped basque and high-waisted knickers, Miley belted out a string of songs from her upcoming album, Bangerz.
The crowd saw all her usual tricks - namely twerking and grinding while sticking her tongue out - but for a brief moment Miley's hard shell seemed to crack.
Miley visibly choked up during her performance of Wrecking Ball, which is thought to be about her ex-fiancé Liam Hemsworth.
The 20-year-old seemed to struggle through the lyrics: "Don't you ever say I just walked away, I will always want you."
It's no surprise Miley has been finding things difficult, as Liam has already moved on.
The Hunger Games actor has been snapped kissing Mexican actress Eiza Gonzalez outside her apartment block.
Earlier in the week - just days after Miley and Liam confirmed their split - he was seen partying with the leggy blonde in Las Vegas.
While all this was going on, Miley was reportedly still messaging her ex.
A source told Life & Style: "She texts him so much, especially super late at night.
"His friends joke about it. Liam doesn’t want to be mean - but he wants to be single."
Not sure how Eiza will feel about claims Liam wants to be single!
After her emotional performance, Miley put on a brave face to hang out with the Kardashian clan.
She also - of course - changed her outfit.
Continuing her white theme, Miley sported a string vest dress, with just some skimpy knickers and sticker nipple covers underneath.
Kourtney and Khloe Kardashian, plus their half sisters Kendall and Kylie Jenner, chatted animatedly with Miley as they spent time together backstage.
Perhaps Miley was bonding with Khloe over their frustration with men, as the Keeping Up With The Kardashians star reportedly recently split from basketball star Lamar Odom.
