Limo Driver Doesn't Remember Giving Reality Show Permission

Fred Busby -- a limo driver -- claims he was taking the star of the show and her cameraman to LAX, when he went into a diabetic coma. Busby says the show aired the footage and portrayed him as drunk ... even though he insists he never signed a release form.

But we now have a release form that appears to show Fred's signature not once, not twice but three times.

The form states, among other things, "I recognize that my signature on this release is a condition of Company permitting me to be a guest/participant in the Programming or both"

We spoke to Fred's lawyer who tells TMZ, "My client does not recall signing any such documents"
