This message hinted to a lot of his fans that his "new chick" is indeed Ariana Grande, after breaking his engagement off to his old chick, "Glee" actress Naya Rivera. It looks like Big Sean may be ready to come out in public with his new girlfriend Ariana Grande, 21, so why haven't they announced to their fans that their relationship is real? "Sean wants to go public with their relationship but Ariana's team is holding her back. They think she's better off keeping the mystery," a source told Hollywood Life. "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," their source said. "They're trying not to let it affect them, but eventually he's going to make her make a choice. He's not going to keep this secret forever." Ariana may be getting closer to revealing the fact - on September 21, she tweeted: "my baby loves me"

J-14.com reports that they have even been caught kissing and hugging each other!

The pair collaborated on her hits "Best Mistake" and "Right There" as well.

"(We) make a lot of music together and the chemistry between me and her when we work is great," 26-year-old rapper Big Sean told MTV News.

"We got more in the works, too," Sean said.

"I feel like her voice is crazy, (just) that big voice that comes out of her is insane," he continued. "I was probably one of the first people to ever tweet about her music."

"We've been friends for years before anything else," he confessed.

Sounds like more than just a friendship has budded between these two.
