LOS ANGELES (AP) --

Ed McMahon, the loyal "Tonight Show" sidekick who bolstered boss Johnny Carson with guffaws and a resounding "H-e-e-e-e-e-ere's Johnny!" for 30 years, has died at a Los Angeles hospital. He was 86.

Publicist Howard Bragman says McMahon died early Tuesday at Ronald Reagan UCLA Medical Center surrounded by his family.

Bragman didn't give a cause of death, saying only that McMahon had a "multitude of health problems the last few months."

Our condolences to McMahon's family and friends.
