RIP

Rea -- who also appeared in "I Love Lucy," "The Odd Couple," and "MacGyver" -- passed away on Saturday from congestive heart failure.

We're told Jake and Josh Harris are currently on board the boat their dad made famous -- the F/V Cornelia Marie because they feel their dad would have wanted them to treat the day like any other day ... and continue to run the family business.

Sources close to the family tells us the boys just wrapped up a successful season of Opilio crabbing and are now headed to Kodiak, AK for cleaning and repairs.

As we previously reported, both Jake and Josh have expressed interest in following in Phil's footsteps ... and captain their own boats one day.

So far, no official cause of death has been released -- but the British tabloid The Sun is reporting that Moore was "drinking heavily" during a bender the night before his body was discovered.

The famous fit club joined Jack's widow Elaine and his son at the Forest Lawn service.

Sal worked for 45 years at Carlo's Bakery in Hoboken, NJ, where the show is taped.

TMZ spoke with Jon LaLanne (pictured right) -- one of Jack's three children -- who told us, "Though we are saddened by our father's passing, the overwhelming response from fans and the media has made us all feel he is still with us."

Jon added, "I plan to carry on the family business. I will be alongside my mother Elaine, my wife Lora, my brother Dan and my sister Yvonne touring the country preaching my father's common sense approach to a longer and better life."

Jon is an accomplished businessman himself -- running a successful surf board company aptly named "LaLa."

LaLanne hosted a popular workout show for several decades, opened a chain of gyms, and created a popular line of juicers.

His agent said he worked out and exercised every day of his life, even up until the end.

23-year-old "Sexy Cora" was reportedly trying to enhance her bra size from an F to a G cup ... when she fell into a coma during the operation and died 9 days later.

According to published reports, the two doctors who performed the surgery have been charged with negligent manslaughter.

Don gave future superstars like The Police and Billy Joel early national exposure -- and also worked with everyone from Carole King and Bobby Darin to Black Sabbath and the Allman Brothers.

In the 70s, he hosted "Don Kirshner's Rock Concert" on ABC.

Her record label posted a statement on their website -- which reads, "It is with great sadness we announce that Trish Keenan from Broadcast passed away at 9am this morning in hospital. She died from complications with pneumonia after battling the illness for two weeks in intensive care."

Nelson was the last surviving member of the cast. The show, which ran from 1952 - 1966, featured David, his brother Ricky (who was also a huge singer), and parents Ozzie and Harriet.

Ricky Nelson -- who's hits include "Garden Party" and "Hello Mary Lou" and "Travelin' Man" -- died at age 45 in a plane crash in 1985.

David -- who died of complications from colon cancer -- is survived by his wife and five children.

Erwin is probably best known to younger audiences for his guest role on "Seinfeld" -- but he appeared in numerous shows, including "I Love Lucy," "Perry Mason," "Leave It to Beaver," "The Twilight Zone," "Gunsmoke," "The Golden Girls," "Growing Pains" and "Who's the Boss?"

Peter died Sunday in a hospital near his English home.

Nominated for an Oscar for his role in the 1993 film "In the Name of the Father," Postlethwaite also starred in movies like "The Usual Suspects," The Lost World" and most recently in "Inception" and "The Town."

Co-Executors John Branca and John McClain fired off a vitriolic letter to the Prez of Discovery -- obtained by TMZ -- in which they accuse the network of operating in "shockingly bad taste ... motivated solely by your blind desire to exploit Michael's death, while cynically attempting to dupe the public into believing this show will have serious medical value."

The Co-Executors are particularly outraged by a print ad, depicting a corpse sprawled on a gurney, covered by a sheet with a sequined glove sticking out.

We're told officials searched Teena's home in Pasadena , CA -- but only found some herbal medication -- and we're not talking marijuana.

We're told an autopsy and toxicology tests will be performed on her body later this week -- but so far, officials are leaning towards the theory that she died of natural causes.

As we previously reported, Teena -- once considered Rick James' protégée -- suffered a grand mal seizure just one month ago.

Relatives found Teena's body Sunday morning at her home. Relatives tell TMZ Teena seemed fine yesterday, when she spent Christmas with her brother. Teena spoke at length yesterday with Lynn, who tells TMZ Teena seemed "fine."

So far it's unclear what caused the singer's death -- but the Pasadena Police Department tells TMZ they do not suspect foul play. They say it looks like Teena died of natural causes. The L.A. County Coroner's Office will perform an autopsy.

We're told Teena had a seizure a month ago, but it's unclear what triggered it.

Marie was nominated for a Grammy four times ... her first top ten hit was "I'm Just a Sucker for Your Love."
