First they got matching cloud tattoos, followed by Pete getting her initials "AG" and her Dangerous Woman bunny ears tattooed on him.
Not long after, he, Ariana and some friends got "H2GKMO" tattooed on their hands.
But before all of that, Pete had to get a huge tattoo dedicated to his ex-girlfriend Cazzie David removed from his arm.
"I did a huge coverup [adding a forest of trees]," tattoo artist Jon Mesa told New York Post's Page Six. "After we were done, I told Pete, ‘Hey, dude, let’s just stop with the girlfriend tats until after [Grande’s] your wife."
Clearly we know Pete didn't take his advice.
Instead he proposed, so we guess he turned that advice on its head.
The tattoo artist continued, "Relationships come and go, and Pete is a really young man. [But] I think that went in one ear and out the other."
He added, "it’s obvious that Pete is super in love with Ariana," so hopefully everything works out for the pair.
