Ed McMahon has passed away at the age of 86, according to KNBC. He died in Los Angeles this morning.

The former "Tonight Show" host is best known as Johnny Carson's sidekick. He was hospitalized in February with pneumonia and other illnesses, including bone cancer.

The star was also embroiled in financial difficulties. A court recently ruled that he owes Citibank $180,000 for debt incurred over four years. In addition, over the past year foreclosure proceedings began on his hilltop mansion.
