The two were first linked a few months after Sean and his former fiancé Naya Rivera called off their engagement in April.
Sean and Grande initially denied the relationship rumors, saying they are just friends.
But the pair has since been seen getting cozy in public and at industry events. They were photographed walking hand-in-hand at an after-party following her appearance on Saturday Night Live. They were caught holding hands on a backstage live feed at the MTV Video Music Awards. And sources told E! News that they spotted Grande and Sean kissing during a late night showing of The Purge at The Grove in Los Angeles.
Sean also made an appearance on Grande’s second studio album My Everything. The two collaborated on the smooth track Best Mistake.
The rumors are rampant they are an item. But Sean and Grande have remained mum about the status of their relationship.
During an interview on the On Air With Ryan Seacrest morning show, Sean gushed about his friendship with Grande. But he wouldn't confirm if the pair are dating. ‘I am going to tell you this: That Ariana is very, very special. She’s very special to me,” Sean said.
