Ariana Grande is nursing a broken heart after splitting from her longtime boyfriend Jai Brooks.

The 'Baby I' singer and her Australian comedian beau haven't officially outright confirmed the split, but they're being pretty obvious about it nonetheless over Twitter. Check out these posts from the past few days from Grande, Brooks (who quotes Ed Sheeran!), her mom, his brother and one of her Arianators:

It's unclear why the pair, who were an incredibly cute couple, called it quits ... but speculation is blaming Grande's publicized smooch with Justin Bieber for the breakup.

Still, the couple posted gushing pictures together on Instagram just this week.

It's not the first time Brooks and Grande have broken up, though. They previously split briefly in February, citing the difficulties of long distance as why their relationship ended. Hopefully they can work it out because we love them together!
