Eminem has blasted Mariah Carey for denying the pair ever dated.

The hip-hop star branded the 'Hero' singer a "bh" while appearing on his own U.S. satellite radio channel, Shade 45.

Eminem - real name Marshall Mathers III - insisted the couple had been an item, despite Mariah denying the claims.

He said: "Me and Mariah did have a relationship for about a good six or seven months."

The 34-year-old rapper also claimed the brief romance fell apart due to their different personalities.

Our personalities collided

He added: "It didn't work. I wasn't really into what she was into, our personalities collided. She's a diva and I'm a little more regular, I guess. That the fact that she denied we ever had something - that's bad."

Eminem was alleged to have dated the pop diva in 2001 when he worked on her 'Charmbracelet' album.

However, Mariah denied his claims, saying: "I knew him, I hung out with him a few times, but nothing sexual occurred. Maybe he thought he'd look bad or something."
