Rocker Sammy Hagar was shocked to see one-time bandmate Eddie Van Halen when the pair attempted an ill-fated reunion in 2004 because the guitar great had turned into a black-toothed, unwashed tramp who lived in squalor.
Hagar agreed to meet with Van Halen at his Malibu, California, home after he had divorced actress Valerie Bertinelli and before he was diagnosed with cancer of the tongue - and he admits it was sobering to see his former pal living like a dog.
In his new biography, Red, the rocker recalls, "It looked like vampires lived there. There were bottles and cans all over the place, the handle was broken off the refrigerator door, and there were spiderwebs everywhere. There was no food.
"He (Van Halen) was sleeping on the floor with a blanket and a pillow. I've never seen a dirtier place in my life."
Hagar reveals Van Halen's attitude had changed too: "(He was) one of the sweetest guys I ever met and he had turned into the weirdest f**k I'd ever seen: crude, rude and unkempt."
The reunion plans didn't pan out and Van Halen, his brother Alex and son Wolfgang eventually hit the road with original frontman David Lee Roth.
The guitarist has since won his battle with cancer, had his teeth fixed and battled alcoholism in rehab.
