Mariah Carey has announced that she’d "rather be on stage with a pig" than duet with Jennifer Lopez.

Mimi put a swift end to speculation that she was planning to collaborate with J.Lo, by insisting it would "never happen" – and then comparing her diva rival to a pig.

When asked about a possible duet the Hero singer fumed to Australian website New Weekly, "I'd rather be on stage with a pig! A duet with Jennifer Lopez and me just isn't going to happen."

So that’s a ‘no’ then?

Mariah recently slammed her ‘diva’ reputation, claiming she’s never been difficult to deal with.

She said: "I am baffled, shocked and appalled when I am called a diva,” she moans. “I've never done one diva-ish thing in my life. The actual definition of a diva is a woman who sings well.

“The secondary definition is a woman who is difficult to deal with. I hope I am the first, but I really don't think I am the second. I don't believe I am truly nasty and act in a bad way."
