Vegan influencer busts cheating boyfriend — thanks to a pepperoni pizza order

It was the ultimate cheat meal.

A vegan influencer redefined “meat lovers” after allegedly busting her boyfriend for cheating on her — thanks to an order of pepperoni pizza.

“I couldn’t believe what I was seeing,” Brazil’s Sabrina Low — real name Sabrina Lourenço — told Jam Press of the revelation, which she made while ordering food from an app on her beau’s phone.

The content creator, who frequently shares sultry pics for her nearly 90,000 Instagram followers, reportedly saw the unexpectedly meaty treat in her boyfriend’s order history.

She found the order suspect, given that he was allegedly a staunch vegan like she was.

That’s when the realization hit her eye like a big pizza pie — the order was for someone else.

“I knew it wasn’t for him,” the scorned woman said, per local media. “We always talked about the importance of being vegan, and that was a big part of our values. I fell in love with him for that exact reason.”

Spying the pepperoni purchase, she said, “was like being punched.”

When Low confronted the slice-buying scoundrel, he initially denied the allegation of infidelity before eventually copping to having a pizza on the side.

“It was then that I realized our relationship was destroyed and, in that moment, the app was my ally to end this lie,” said Low.

However, she didn’t reveal whether she eventually dumped him.

Ultimately, Low said she felt “betrayed” because she knew her man would “never eat meat.”

In other words, he might cheat on his girlfriend — but never on his diet.
