The imaginary, non-existent celibrity couple of Ariana Grande and Justin Bieber. Many people confuse it with Jai Brooks and Ariana Grande, her REAL boyfriend. Jariana is wishful thinking, and it is never going to happen, because Ariana loves Jai, not Justin.
Person: OMG Jariana is so cute!!!!!
Person 2: No they're not, they don't exist
