LOS ANGELES (AP) — Ed McMahon, who for decades appeared as Johnny Carson's sidekick on "The Tonight Show," is fighting to avoid foreclosure on his multimillion-dollar Beverly Hills home, according to published reports.

The former "Star Search" host was $644,000 behind on payments on $4.8 million in mortgage loans when a unit of Countrywide Financial Corp. filed a default notice Feb. 28 with the Los Angeles County Recorder's Office, The Wall Street Journal first reported late Tuesday.

McMahon, 85, has been a pitchman for the American Family Publishers' sweepstakes.

However, he has been unable to work as a pitchman for various products since he broke his neck 18 months ago, said his spokesman, Howard Bragman.

"There are plenty of people affected by the weak economy, bad housing market or bad health," Bragman said.

McMahon has been in "very fruitful discussions" with the lender to resolve the situation, Bragman said. But it's unclear whether McMahon and his wife, Pamela, will remain in the home.

A telephone message left for Countrywide early Wednesday was not immediately returned.

The six-bedroom, five-bath house is in a hilltop gated community overlooking Mulholland Drive called The Summit and is listed for sale at $6.25 million. It has been on the market two years, according to real estate agent Alex Davis, who has the listing.

The house is near that of pop star Britney Spears, which doesn't always work in its favor.

"When we were trying to sell the house one time, there were about 100 paparazzi there," Davis said.
