Big Sean dished about his relationship with Ariana Grande, revealing “great chemistry” is what draws him to her.

The rapper gushed about Grande during an interview with MTV News. Big Sean, 26, and Grande, 21, were spotted holding hands during the MTV Video Music Awards back in August.

Sean claims he developed a friendship with Grande before “anything else” happened between them.

“I was probably one of the first people to tweet about her music; me and her been friends for years before anything else,” he told MTV News.

Big Sean added, “Me and her make a lot of music together and the chemistry between me and her when we work is great.”

The same can’t be said about the rapper’s relationship with actress Naya Rivera. Big Sean has reportedly dissed his former fiancé in new song titled “I Don’t F**k With You.”

According to TMZ, Big Sean wrote the song about Rivera, allegedly calling her a “little stupid a** b***h.”

“I don’t give a f**k about you or anything that you do,” Big Sean stated in the song. “I heard you got a new man. I see you taking a pic. Then you post it up thinking that it’s making me sick. B***h I got no feelings to go. I swear I had it up to here I’ve got no ceilings to go. I mean for real, f**k how you feel.”

Big Sean also goes on to say he wakes up “celebrating” because he “dodged a bullet from a crazy b***h” in the new track.

Rivera, 27, married Ryan Dorsey, 30, in a private ceremony in July. The couple released a statement shortly after tying the knot.

“We feel truly blessed to be joined as husband and wife,” the couple said. “Our special day was fated and everything we could have ever asked for.”
