Adele Says She Developed Jock Itch from Sweating 'a Lot' in Her Spanx Onstage

"I sweat a lot, and it doesn't go anywhere, so I basically am just sitting in my own sweat," the Grammy winner explained

Adele is getting candid about the less glamorous side of show business.

The "Rolling in the Deep" singer, 35, explained to fans during her Las Vegas show over the weekend that she had been prescribed jock itch ointment for sweating "a lot" onstage in her Spanx.

"I sweat a lot, and it doesn't go anywhere, so I basically am just sitting in my own sweat, so my doctor [diagnosed] me [with] jock itch," she said in a video shared on social media.

"Jock itch, that sounds like I'm a big Nuggets fan, doesn't it?" joked the Grammy winner, referring to the Denver-based NBA team that just won the NBA Finals. "It looks like I'm a big athlete, right?"

The fungal skin infection, commonly found among athletes, is an "infection that causes an itchy rash in warm, moist areas of the body," such as the groin and inner thighs, according to the Mayo Clinic.

"I have to squirt it on myself," she said before telling the crowd, "I don't know why the f--- I just told you that!"

She further teased, "Adele's got body acne!"

In March, Adele revealed that she was extending her Las Vegas residency Weekends With Adele at the Colosseum at Caesar's Palace.

"Playing to 4,000 people for 34 nights is not enough and I know that, I know it's not enough," she said at the time. "So I am coming back."
