Lady Gaga Plummets Backwards Off Stage After Dancing With Fan

It was not a "perfect illusion" when Lady Gaga fell off the stage during her Las Vegas residency, "Enigma," on Thursday night.

The mishap occurred after the star invited a fan on stage with her.

Video from an audience member shows a man holding Gaga on stage, jumping up and down with her in his arms. Gaga's legs were wrapped around the fan, so when he fell, she took the tumble with him.

Both plunged to the floor as a result.

The pair took a tumble after dancing on stage together.

Moments after the fall, Gaga was back onstage with the fan.

"You promise me you're not gonna be sad about that, right?" she said.

"I promise," he responded.

The singer did not appear seriously injured by the incident. Another video taken by an audience member shows her performing "Bad Romance" shortly after the fall. "The level of professionalism... far too much!" the fan wrote.

Several fans posted video of the fall and Gaga's return to the stage on social media.

While the show went on, Gaga did ice her entire body after the concert – something that she called her "post show routine." She shared three photos of the ritual: "ice bath for 5-10 min, hot bath for 20, then compression suit packed with ice packs for 20."

She also shared her "pre-show" routine: swimming laps in a pool. On Instagram, she dubbed herself "Gaga Phelps."

The Oscar-nominated actress has been known to deal with fibromyalgia, a condition that causes chronic pain. She has tried several treatments to ease the soreness in the past, as seen in her documentary, "Lady Gaga: Five Foot Two."

The cause of fibromyalgia is unknown, but doctors have identified a number of risk factors, which usually occur during middle age. Ahead of the documentary's 2017 release, Gaga said she wished to "raise awareness & connect people who have it."
