Ariana Grande Radio

It may have started out with a music collaboration or two, and holding hands backstage at the MTV VMAs, but rumors about whether or not Ariana Grande and Big Sean are dating have kicked into high gear now. 

A new photo shows Ariana and Big Sean on The Revenge of the Mummy ride at Universal Studios in Hollywood ... and they're totally KISSING!!

While everyone else around them has a scared expression on their face and hands in the air, the rumored couple locked lips, thus potentially proving they are indeed an item. It also looks like they were holding hands walking out of the ride together. 

Ariana and Big Sean were also spotted holding hands as they left an "SNL" after party at a New York City club.
