Singer and former Victorious actress Ariana was pictured holding hands with Sean while the pair were backstage at the MTV Video Music Awards on Sunday (25 August).
The picture seemingly confirmed weeks of speculation that the two friends and collaborators are indeed in a relationship.
On Tuesday (26 August), 21-year-old Ariana spoke to Ryan Seacrest on his radio show On Air, and it wasn't long before she was grilled about whether there is any truth to the rumours.
"I mean, I guess, curiosity man, it'll kill you," Ariana said, as she attempted to dodge the question.
"I don't know what to say, Ryan. Why are you doing this me? I'll tell you. I'll tell you when we're not on the air. I trust you. I've known you a long time. I don't know about these millions of people listening in right now."
Ariana didn't outright deny it, but is it enough proof that Sean is her new beau?
Pop princess Ariana, who has previously dated The Wanted singer Nathan Sykes and Australian comedy star Jai Brooks, is currently dominating the music charts worldwide with the release of her second studio album, My Everything.
Sending a sweet message to Ariana, 'Too Fake' rapper Sean said on Instagram: "Ari's #1 in 80 countries! So great when good things happen to good people. I'm more than proud of you @arianagrande and grateful to be apart of it!"
On Ariana's album, Sean features on her single 'Best Mistake' and provides background vocals on 'Problem' with Iggy Azalea. Last year Sean and Ariana also collaborated for her single 'Right There'.
Sean was perviously engaged to Glee star Naya Rivera, but they ended their relationship in April this year, and Naya surprised fans just three months later by revealing she married long-time friend Ryan Dorsey on 19 July.
