The couple is no stranger to public displays of affection (hardly a day goes by without one of them declaring their love in the comments section), but Pete took things up several romantic notches for Ariana's 25th birthday.
First, there was this, which Pete captioned "Happy birthday to the most precious angel on Earth! You're my favorite person that ever existed :) I love you sm."
But because one birthday post wasn't enough, he also shared the below gem: "One more for the queen. Words can't express what a real fucking treasure this one is."
Not to be outdone in the PDA department, Ariana also hopped onto her Instagram Stories to tell everyone that she doesn't have a birthday wish BECAUSE SHE HAS EVERYTHING SHE WANTS, SOB.
Cool, my relationship is also just like this! It's fine! Everything is fine!
