After two years of dating, a couple claims to be facing a very uncomfortable situation.
TikTok users Carley and Mercedes have taken to the video-sharing platform to share their potential problem and ask for some advice from their followers.
In a clip which has been viewed over eight million times to date the girlfriends from Canada share how they recently found out their mothers both slept with the same man.
They then ask their followers if they should take a DNA test to find out if they are actually half-siblings.
"DNA test is on the way," the women confirmed in a follow-up video, using the hashtag siblings or dating.

It's unclear if the couple are being serious or pranking their followers, but they keep the story up in several other videos.
In another, they asked if they should continue their relationship if they were in fact half-sisters, writing: "If we're actually related is it wrong to stay together?"
Their account has over 616,000 followers and many people shared their shock in the comments - with some admitting they thought the two did look rather alike.
One person said: "DUDE PLS I'VE ALWAYS THOUGHT U LOOK ALIKE."
Another replied: "I have no idea who you guys are and I immediately thought you were sisters before reading the text."
A third wrote: "I just watched a few of your videos and I say get the tests done ASAP. I'm genuinely scared for y'all."
Someone else said: "You guys look like twins. LMAO I'm so sorry."
A different user added: "I feel like this is a joke, but you do for real look exactly the same."
