A couple has revealed that they could actually be half-sisters.
Despite the bombshell news, the TikTokers are still considering staying together - even if they do turn out to be related.
As well as being TikTok stars, Canadian couple Carley Gonschior and Mercedes Stewart also run an OnlyFans account together. In their social media videos, they are often open about the fact that neither of them grew up with a father in their lives.
However, this took on a whole new significance when - two years into their relationship - Carley and Mercedes found out that their moms both slept with the same man, and therefore that they might have the same biological dad.
The pair took to TikTok to share the concerning discovery with their 619,000 plus followers in a now-viral video that has racked up over 8.4 million views.
"When u find out 2 years into dating that ur moms both slept with the same guy," they wrote onscreen in the clip. The couple also added a caption asking followers: "Should we take a DNA test?"
Unsurprisingly, people were stunned by the revelations. Thousands took to the comments section to share their opinion, with many pointing out that Carley and Mercedes do share a striking resemblance with one another.
"DUDE PLS IVE ALWAYS THOUGHT U LOOK ALIKE," one viewer wrote, while another agreed: "That could explain why you two look like sisters."
"If we’re actually related is it wrong to stay together?" Carley and Mercedes asked their followers in a comment. The response was mixed. One person thought it would be okay, saying: "The only problem is society. They can't have kids together so what issues can it cause."
Another was outraged, writing: "Are you serious? Are you trying to justify INCEST?"
In later videos, the couple appears relatively unphased by the prospect of being siblings. In one, they jokingly discussed doing a DNA test - but worried that if they kissed during the 24 hours before the results might be affected.
In other clips, they continue to cozy up to each other and joke about their bizarre scenario.
As for the results of the DNA test - those are still yet to be revealed.
