When we initially heard that Ariana Grande and Jai Brooks broke up and that she was rebounding with Big Sean, we couldn't believe it. Now, even more people are claiming that Ariana is dating her "Best Mistake" collaborator — and that they're closer than ever!

"They have been friends since they made the song together," a source told E! Online. "They have been spending more time together and recently have been getting very close. They are both doing great."

Since Ariana and Jai arrived separately at the Teen Choice Awards — Jai stuck with his Janoskians bros and Ariana brought her grandma — it looks like Jariana might have really ended. Of course, neither Ariana nor Sean are speaking up about rumors that they're an item, so we can't tell if they're really good friends, or if there's something more going on between them. We need to know!

Do you think that Ariana is dating Big Sean? Are you still bummed that she's not with Jai? Let us know in the comments!
