Things have gotten nasty.

Ariana Grande didn't appreciate ex Pete Davidson joking about their quickie engagement in an SNL preview, and she let him know it by putting him on blast on Twitter!

In the teaser, the comedian turns to singer Maggie Rodgers and proposes marriage. "Hey, Maggie. I’m Pete. Want to get married? No? 0 for 3," he quipped.

The "Sweetener" songstress just couldn't bite her tongue over the diss.

"For somebody who claims to hate relevancy u sure love clinging to it huh?" she tweeted shortly after it aired. "Thank u, next," she added. She has since deleted those messages.

Sources had been saying the split was amicable and the two had simply realized they were moving too fast, but clearly that's not the case!
