We're not quite done freaking out over Ariana Grande's latest collaboration, "Rain On Me" with Lady Gaga, that dropped on Friday (May 22).We also can't forget that Grande currently holds the top spot on the Billboard Hot 100 with "Stuck With U" alongside Justin Bieber. We stan a collab queen!With these new collaborations in the air, we're dreaming about all the other team-ups Grande could potentially cook up in the future.
