KHLOE Kardashian has been pictured rubbing Usher's abs and nipples during a wild night in Las Vegas.
Khloe, 38, flew to Sin City on Saturday with her big sister Kim Kardashian and some pals to watch Usher perform live as part of his residency.
The siblings appeared to be having a great time and shared plenty of footage on their Instagram Stories.
Good American co-founder Khloe had ditched her underwear for the occasion and showed off her svelte figure in a skintight cut-out dress.
As Usher performed some of his biggest hits, the two sisters danced against one another as they flaunted their best moves.
At one point, 44-year-old Usher entered the audience and stopped to perform right in front of Kim, Khloe, and their pals.
Khloe clearly got very excited and was caught on camera stroking the singer's bare chest.
In another shot, either Khloe, Kim, or their friend Kimora Lee Simmons appeared to be caressing his bare nipples as he grinned from ear to ear and continued singing.
Khloe's cheeky behavior comes after fans continued to speculate about whether or not she is back with her cheating ex-boyfriend Tristan Thompson.
At the beginning of April, the two were spotted hanging out together in Rialto, California.

"He drove up with Khloe to Palm Springs early last week and was there until Sunday with their kids, Kris [Jenner], Kim, and the whole gang.
"They were staying at Kris and Kylie's side-by-side homes and Bright Event Rentals decked out the entire place for a huge Easter party."
"Kim's jet was going back and forth all week from LA to Palm Springs, which is 33 minutes each way, but Khloe and Tristan spent eight hours doing the round-trip together," the source added.
