Kim Kardashian's fans are concerned for the star.
According to outlets including The Sun, the mom-of-four deleted a video from her TikTok account after many followers were alarmed about a "weird bruise" on her chin and jaw.
In the clip - which appears to have been filmed by Kim's nine-year-old daughter North - the pair can be seen dancing around in a parked car while Drake's 'One Dance' plays in the background.
Kim and North often post videos of themselves hanging out and lip-syncing to songs on their shared TikTok account, @kimandnorth.
However, eagle-eyed fans were quick to notice an odd detail in this video that set it apart from the mom-and-daughter duo's usual TikToks.
As Kim danced while holding a coffee in one hand, there appears to be a dark mark or bruising along her jawline.
Check out the 'bruise' below:Despite the mark only being visible for a few seconds, the clip was deleted soon after it was shared.
However, it wasn't removed fast enough to stop quick-fingered fans from taking screen recordings of the TikTok and then resharing it to other social media platforms.
The video prompted concern among fans, who took to the comments section to speculate as to what could have caused the mark - and why Kim was so keen to hide it.
One commented that they could clearly see a "weird bruise" on the reality star's face, according to a report by The Sun.
Meanwhile, many assumed the mark was the result of fillers or botox injections.
"She probably had some fillers/botox done which can bruise depending on [what] you have done," one wrote. Another agreed, commenting: "Cosmetic injectables bruising."
Others theorized that the mark could be a sign of Kim's psoriasis, writing: "I think it could be her psoriasis acting up again."
One person thought it could be nothing more than a sign that North - who has a passion for wound special effects make up - has been practicing on her mom. "Remember North is a trauma 'make-up' artist," they wrote.
And another thought it could even hint that the beauty mogul is in a new relationship. "Maybe it’s a passion mark," they commented.
