A couple who have been dating for two years are considering taking a DNA test after allegedly discovering their mothers both had a sexual encounter with the same man.

The couple, Carley and Mercedes, shared the shocking revelation to their almost 600,000 followers on TikTok, revealing they could possibly be half-sisters and have the same biological father.

The pair, who also create content for their OnlyFans platform, claimed they recently discovered that their mothers both had sex with the same man. In a clip that has since been viewed more than 7.6 million times, the women, who bear a strong facial resemblance to one another, lip-synched along to audio that said: "Funny, yes. But not funny 'haha', funny weird."

"When you find out two years into dating that your moms both slept with the same guy," the couple captioned the clip, adding: "Should we take a DNA test?"

In the comments, Carley and Mercedes asked their audience: "If we're actually related, is it wrong to stay together?"

The alleged admission has caused a storm of controversy among viewers, many of whom agreed that the two look uncannily alike.

"Dude please I've always thought you look alike," one declared, with a second agreeing: "That could explain why you two look like sisters."

"Take one [a DNA test] immediately," another instructed, to which the couple - and could-be sisters - replied: "We're scared."

"I have no idea who you guys are and I immediately thought you were sisters before reading the text," another weighed in.

Others noted that if the loved-up duo are truly happy, perhaps they should remain "blissfully ignorant".

However, many others have called the legitimacy of the couple's wild claim into question, with some wondering whether the video was merely a stunt to generate more attention to their account. Many questioned if it was all just a joke for views. 

"I can't tell if this is real or just a TikTok joke…?" one mused, with a second adding: "I feel like this is a joke but you do for real look exactly the same."

Another wondered: "What if they’ve been sisters the whole time and have been catfishing us into believing they’re dating?"

In a follow-up clip, the couple lip-synced to audio alongside the caption: "Us happy in our two-year relationship - finding out we might be half-sisters."

"Siblings or dating plot twist… maybe both?" they added.

In another video, the couple implored their viewers if they should "even risk" getting a DNA test and compromising their relationship. However, a third video with the same premise had some of their audience scratching their heads. 

"You’ve asked a few times now, pretty sure consensus is yes," one hit back.

"Three videos saying the same thing," another noted, with others agreeing: "[There's] a lot of views. Whether they made this up or it's real, they're milking it" and "I'm starting to believe that this is a hoax for views cause they look so much alike."

"I think if you don't take the test you will regret not knowing," another suggested.

At the time of writing, the couple has shared another video claiming they have ordered the tests, but it can take a few weeks for the results to be processed.
