Ariana Grande and Ethan Slater have been a controversial couple from the start... but they always seemed happy. Has that stolen joy all run out?? Fans have been squinting their eyes at the relationship for some time, wondering what was going on. Ari and Ethan haven't had a public outing together for months, since they went to the theater in April. They've always been a private (or should we say secretive?) couple, but this was concerning. And then of course there was the kiss of death - Ari posed for a photo with BLACKPINK singer Rosé at the MTV Video Music Awards last month.
