Ariana Grande and Pete Davidson The Internet has been going crazy for these two! Ariana Grande and Pete Davidson had a whirlwind romance and quick engagement! Davidson proposed to Grande with an engagement ring designed by jeweler Greg Yuna from New York City. The ring is a pear-shaped engagement ring that features a 3 carat center stone. The couple began dating in May 2018, soon after Grande's split from Mac Miller and Davidson's split from Cazzie David. Nick Jonas and Priyanka Chopra This couple has been incredibly secretive about their relationship, which is why their engagement came as such a shock! There have been very few details about this couple's romance, but it is rumored that Jonas closed down a New York City Tiffany Store in order to choose the perfect ring or his future bride. These two still don't have any photos together on their personal social media accounts...yet.
