Bosses at diet product company Slim-Fast have offered rapper Eminem the chance to become their next spokesmodel, after learning he's battling weight problems.

The superstar was recently hospitalised after suffering from heart problems arising from a bout of pneumonia.

And, in her new book, 'My Son Marshall, My Son Eminem', the rapper's estranged mother Debbie Nelson reveals the elusive rapper has ballooned in weight.

She writes: "His face has broken out in pimples and he's put on so much weight that he's causing all sorts of other health problems for himself."

And Slim-Fast chiefs want to help.

A spokesperson says: "Slim-Fast is a program that can really work for someone like Eminem; It's a do-able and flexible approach.

"Slim-Fast would love to offer Eminem product and assistance to help him become a potential S-F success story."
