Big Sean is not writing a diss song aimed at ex-girlfriend Ariana Grande. Responding to a HollywoodLife report claiming he "plans to write and release a song dedicated to bashing her," the rapper's rep has told Gossip Cop the story is "not true."

Citing a "source," HollywoodLife says that Sean "can't wait to put his relationship with Ariana on blast in a song." The site points out that the Detroit native wrote "I Don't F**k With You" which was allegedly aimed at Naya Rivera following his split from the former "Glee" star last year.

Sean and Grande broke up after just 8 months of dating. While the 26-year-old MC has denied he'll write a song about her, Grande will still be a subject of a former lover's song. Her other ex Nathan Sykes recently said that he'd penned a "very nice breakup song" inspired by their own relationship for his upcoming debut album.

"It's not really that heartbreaking - it's very emotional. It's just a very nice breakup song," he told MTV News. "I'm one of those really annoying people who never holds grudges [against] anyone, because what's the point? There's no point. It's really boring and it takes up so much energy - just draining. So it's an nice breakup song, but really emotional."
