Madge to Guy -- You're a Retard

Without naming names, she intro'd her song "Miles Away" by saying it was for the "emotionally retarded ... You might know a few people who fall into that category ... God knows I do."

But it could be Madge who ends up looking like a bigger 'tard because she didn't sign a prenup -- and could have to shell out as much as $200 mil to Guy, even though he's being quoted in one Brit tab saying he doesn't want a penny of her cash.
