The entirety of their relationship has been nothing but love and affection, so we've been wondering... will Ari follow the celeb code of keeping her last name, or will she take Pete's?
WELL... we have proof that she will hyphen her last name onto Davidson!
Before she could admit that herself, eagle-eyed fans noticed the bracelet Pete was wearing at the 2018 MTV VMA's yesterday. On it, the initials "AGD" can be seen... "Ariana Grande-Davidson"!!
But talking to Beats 1 Radio just recently, Ariana revealed she wanted to keep the 'Grande' part for her grandfather.
"I have to keep Grande because of my grandpa," she said. "I think of him with everything I do in it and he was so proud of our name, I should keep it."
So that's that. She is going to become Ariana Grande-Davidson!
