It's been just barely 24 hours since news broke that Ariana Grande and Pete Davidson are engaged after a mere few weeks of dating — and less than a month since each of them split with other longtime partners.

(For the record, neither star has outright confirmed their engagement, but they haven't denied it either, and Grande has certainly been playing along on Twitter).
