Ariana Grande and Pete Davidson
Some couples, like Jessica Biel and Justin Timberlake, take their time, while others rush into it. Ariana Grande’s proposal came only after a few weeks of dating Pete Davidson. The diamond ring Davidson gave her was estimated $100,000.

The couple’s breakup came as quickly as the engagement, though, as they broke it off before getting married. This time Grande returned the ring to Davidson, admitting that the relationship was too much too fast.
