Ariana has turned 25 today and her fiancé has decided a soppy social media post is the best way to mark the occasion.
He's shared this tribute to his wife-to-be on Instagram, describing her as his "favourite person".
It comes just days after Pete confirmed their engagement during an appearance on The Tonight Show Starring Jimmy Fallon.
They seem to have had a whirlwind romance, only going public with their relationship last month.
