Ariana Grande and Big Sean are quickly becoming Hollywood's cutest couple even though the singers have yet to publicly confirm their relationship. The two have been attached at the hip lately and were recently spotted sharing a kiss on a scary Halloween ride.

Grande and Sean enjoyed a date night on Oct. 4 at Halloween Horror Night at Universal Studios and were caught locking lips on the Revenge of the Mummy ride. The lovey-dovey photo quickly started making the rounds online.

The couple was first romantically linked back in August after fans spotted them catching a movie together. Since then the 21-year-old "Problem" singer and Sean, 26, have been spending a lot of time together.

They were seen holding hands backstage at the MTV Video Music Awards and again after Grande's performance on "Saturday Night Live!." Grande recently addressed the dating rumors during an interview with Ryan Seacrest.

"I mean I guess [we're dating]," she said on "On Air with Ryan Seacrest." "Curiosity man, it'll kill you. I don't know what to say, Ryan. Why are you doing this to me? I'll tell you when we're not on air. I trust you. I've known you a long time. I don't know about these millions of people listening in right now."

Big Sean later appeared on the radio show and was also asked about the romance.  

"I am going to tell you this: Arian's very, very special. She's very special to me," he said. "Everything she has going on is good with her. Everything I have going on is good with me. Everything between me and her is good, and I'm hoping to leave it at that."

According to Hollywood Life, the couple may be playing coy to romance rumors on purpose. Reportedly Sean is ready to go public with the relationship but Grande's management is urging them not to.

"Sean wants to go public with their relationship but Ariana's team is holding her back," the source said. "They think she's better off keeping the mystery. They would actually prefer her to be single but she's way too into Sean to break up with him for the sake of her career."

"He's cool right now keeping it private but in some ways he does resent it, so that's something that's stressful for them right now," the source added. "They're trying not to let it affect them but eventually he's going to make her a choice. He's not going to keep this secret forever."
