Fans reacted in shock after controversial YouTubers Jake Paul and Tana Mongeau announced their engagement after two months of dating.

Paul proposed to Mongeau last weekend while they were in Las Vegas celebrating her 21st birthday.

The news was announced on the 21-year-old’s Instagram Story, revealing the giant diamond ring that Jake proposed with.

She captioned the vid: “I’m engaged @JakePaul.”

Suss it out below:

Punters were instantly skeptical about the union, with many followers questioning whether or not it’s legit.

When a fan asked if the proposal was a prank (bearing in mind that Jake is a notorious prankster and Tana conned a multitude of fans with the aptly titled TanaCon), she responded, “it’s not. i’m engaged. holy fuck.”

But according to multiple ring experts, the images seen on social media present some red flags.

Ira Weissman, founder of The Diamond Pro, told E! News that the ring looks fake as fuck so either the pair plucked out a cheapo ring to trick fans into believing their yarn, or Jake shortchanged his fiance with a knock-off.

“Nothing is a sure thing without seeing the ring(s) up close, but everything about this little clip says ‘fake.’ You can see the exaggerated sparkling light reflecting off of something in the bottom right of the frame in the beginning of the clip,” Weissman told the publication.

“This is exactly what you would want to use to try to enhance the sparkle of a simulated diamond to make it look like the real thing. Plus, the glassy look of the very large center stone as it’s brought closer to the camera also points heavily towards it being a cubic zirconia.”

One savage jewellery expert also told the publication that Tana most likely used that tacky Kira Kira app to amp up the sparkle on the “lifeless stone”.

“Whether or not Ms. Mongeau’s engagement ring is real, a rectangular cushion cut center stone is always an excellent choice!” Expert Lauren McCawley told the publication.

“However, the Kira Kira app can only add so much sparkle to a lifeless stone; this is very like a simulant (CZ) or a lab-created white sapphire, which retails around $200.”

I reiterate: Either the devious internet personalities are scamming us, or Jake is scamming Tana.

Either way, someone’s getting scammed here and I don’t like it.
