Eminem's grandmother BETTY KRESIN has blasted the rapper for remarrying his ex-wife KIMBERLY yesterday (14JAN06) - insisting his spouse has "brainwashed" him.

Kresin boycotted the ceremony in Michigan and is enraged the superstar, real name MARSHALL MATHERS III, has taken back his "nasty" former love.

She fumes, "Boy, has he made a big mistake. No pre-nup or nothing.

"She'll take everything and leave. Kim is a nasty, mean woman.

"We've never been anything but nice to her but she's turned Marshall against us. I think she's very controlling."

Mathers originally wed Kim in 1999, but filed for divorce just 14 months later.
