He can't believe his good fortune!

Pete Davidson made an appearance on Howard Stern's Sirius XM radio show on Monday, and opened up about how he and fiancee Ariana Grande first got together following their respective breakups from Cazzie David and the late Mac Miller.

"Timing, I feel like, is everything. We both were in a similar situation at the same time," the SNL star explained.

"You’re both broken up. You were dating Larry David’s daughter for two years, serious relationship. You broke up for whatever reason, she was with that guy Mac Miller and you both break up," the shock jock clarified while Davidson nodded in agreement.

What about the first time he laid eyes on his lady love? According to him, sparks flew in the SNL writer's room before she appeared on the show.

"When she left, I was like ‘What a f—king idiot I am. I don’t even remember, I was just staring at her. And my boy Dave, who worked there at the time, we were just like, ‘What the f—k is this thing? It’s like a robot,’” he gushed.

Their manager Scooter Braun eventually played matchmaker!

"Booking my career and wife. I was down in the dumps and he came to visit me at SNL … It was a rough time. It was an assortment of things, an assortment of s—t. I just think some people are meant to be together and some people aren’t. Even if they’re good people or not. Some people just aren’t good in relationships together. I just think we’re supposed to be together," he added.

He's one smitten kitten!
