But the fast-paced relationship proved to be short-lived, with news breaking Sunday that the pair called off their engagement and ended their relationship.
Last Friday, Grande released a music video for her new single "breathin", starring the couple's pet pig, Piggy Smallz.
"Someone I'm very close to was supposed to come sing for you today, and because of things that she's going through, she couldn't be here today", he shared. "Like, if we break up, and we won't - we will - but we won't. It's like the weirdest, coolest thing that's ever happened".
Not everyone was supportive of the couple's relationship. "Do you know how insane that is? This is what I want". At the time of writing this, the breakup appears to be amicable and neither have spoken about it publicly.More news: At least 8 climbers dead after snowstorm in Nepal, police say

The pop star took to Twitter on Monday morning to reveal that she would be performing for a special 15th anniversary performance of the Broadway musical Wicked, although she failed to mention her romance with Pete. The conversation strayed onto the topic of prenups, and Davidson joked that while Grande pays $60,000 for rent, he just stocks the fridge.More news: Hurricane leaves Florida’s Mexico Beach in shreds
