Eagle-eyed X fans quickly bombarded Twitter asking if the singer accidentally flashed more flesh than she bargained for...
Cheryl Fernandez-Versini took to the stage on Sunday night to perform her new single I Don't Care, but her performance seemed to be eclipsed by Twitter asking if she accidentally suffered a nip-slip.
The star was rocking a gaping white top with a sheer panel and white shorts, but not long into her performance it looked like she came close to flashing a bit more flesh than bargained for.
Eagle-eyed X Factor fans quickly hit Twitter to have a little big natter about it.
"Anyone think there was a nip slip there from Cheryl?" one person asked, and then there was, "Pretty sure cheryl just had a nip slip #rewind."
While another wrote, "Cheryl loves a nip slip."
And then there was the jokers: "Cheryl nip slip is everything G'wan love."
The singer hit the stage after John Legend to perform the new track, which went straight in at number one.
On the night, Cheryl waved bye to one of her two remaining girls after Lola was axed from the show following the deadlock with Stereo Kicks.

And when she wasn't risking flashing her cleavage, the singer was looking her usual effortlessly stunning self in a black dress with figure-hugging top and floaty skirt, which showed off her tanned and toned legs and a hint of cleavage.
After last night's scraped back 'do, the star opted to wear her hair loose and wavy and teamed the look with black heels.
Meanwhile, Mel B ditched the bold colours and covered up in a black jumpsuit with high neck and glittery beaded scarf.
The former Spice Girl also changed up her hairstyle and wore it down, and added an injection of glamour to the look with huge diamond earrings.
If you were expecting jaw-dropping gowns, you'll be left disappointed.
Who do you think won the fashion face-off tonight? Judging by Twitter reactions, we think it was Chery, but let us know what YOU think below.
