In honor of Ariana Grande's birthday, her fiancé Pete Davidson is proving his love for the pop singer by showering her with love on Instagram. In a series of PDA-filled photos, the SNL star gushed about Ariana — and TBH, we are obsessed with this couple. Watch the video above to see Pete's birthday dedication to Ariana.

"Happy birthday to the most precious angel on earth! You’re my favorite person that ever existed 🙂 I love you sm," he captioned one of the heartfelt pics, before adding, "One more for the queen. Words can’t express what a real f–king treasure this one is." Ariana was also feeling the love and responded, "I love you so much." Fans were quick to defend their love on the social media platform — and shut down haters in the comments section.

"Live your best lives guys," one follower wrote. Another agreed, adding, "When you know, you just know…" Pete and Ariana surprised everyone when they announced their engagement after just weeks of dating — Pete had recently split from his girlfriend of two years Cazzie David while Ariana was linked to rapper Mac Miller until right before they went public — but that hasn't stopped the comedian from gushing about Ariana any chance he gets.

"I feel like I won a contest. So sick." Pete told Jimmy Fallon of the relationship. "It's f–king lit, Jimmy." He also made his love for Ariana permanent with three tattoos in her honor, including one matching ink that reads, "H2GKMO," which seemingly stands for "Honest to God, knock me out." Not surprisingly, his tattoo artist warned Pete not to get the pieces right away. "After we were done, I told Pete, ‘Hey, dude, let’s just stop with the girlfriend tats until after [Ariana's] your wife.’ Jon Mesa told Page Six. "Relationships come and go, and Pete is a really young man. I think that went in one ear and out the other." Keep the pics (and tats) coming!
