Eminem is once again determined to become the real Slim Shady by “cutting new tracks with Dr. Dre”, reveals Daily News.

The rapper has ballooned in weight over recent months and even had to go to hospital for pneumonia and heart problems.

But now the superstar is back in the studio - and desperately fighting the flab.

Insiders say Eminem, real name Marshal Mathers III, as hired a personal trainer and “is working out every day to get rid of the extra weight”.

More excitingly for fans, the reclusive Detroit rapper “has been cutting new tracks with Dr. Dre”, the insider revealed. “They still have a ways to go, but so far it’s really good.”

The album should be out by the end of the year or early next year - by when Eminem is aiming to be in great shape again.

A spokesperson dismissively said: “He’s always in the studio and has worked with a trainer before.”
