Ariana Grande and Chris Brown certainly heat things up in their new video "Don't Be Gone Too Long".

There was definitely a sexy chemistry between the two and Big Sean can't help but feel jealous!

Even though the two have yet to make their relationship official, it's quite obvious that Ariana and Big Sean are dating. Just last month, the couple had been spotted holding hands backstage at the MTV VMAs. Also recently the two had been showing off a lot of PDA during the iHeartRadio Music Festival. It's no surprise that the rapper was a "bit annoyed" when he watched the steaming video of Ariana and Chris.

A source tells Hollywood Life, "He watched it once and is not really interested in watching it again. He definitely seems to be a little jealous about it, but he is making sure not to show Ariana that he is jealous."

But it looks like Ariana has been making up for it by posting their first photo on Instagram. She shared a picture of herself hanging out with her new love behind the scenes and it looks like things are getting pretty serious between the two.

Big Sean had been the first one to admit that their friendship had developed into "something even more special".

He tells MTV News, "Me and her make a lot of music together and the chemistry between me and her when we work is great."

The duo had collaborated on "Big Mistake" and "Right There". But Sean says there's still a lot in store for the two of them.

"We got more in the works, too. I feel like her voice is crazy, just that that big voice comes out of her is insane. I was probably one of the first people to tweet about her music; me and her been friends for years before anything else."
