RIP

Just hours after witnessing a murder/suicide via FaceTime, Floyd Mayweather decided to get out of his house to sit courtside at the L.A. Clippers basketball game Monday night.

Floyd actually appeared to be in a pretty decent mood considering the circumstances ... shaking hands and talking with Clippers stars Chris Paul and Jamal Crawford before they took on the Phoenix Suns at Staples Center.

As TMZ first reported, Floyd was on the phone Monday morning with rapper Earl Hayes when he killed his wife, VH1 star Stephanie Moseley, and then himself.

Floyd Mayweather is reeling tonight ... because he was on FaceTime with one of his best friends when the guy pulled out a gun, shot his wife and then killed himself ... TMZ has learned.

Sources tell us ... rapper Earl Hayes called Floyd on FaceTime Monday morning in a rage, over claims his wife -- VH1 star Stephanie Moseley -- had been unfaithful.

According to our Floyd sources, Earl said he was going to kill his wife. The champ was pleading with him to get a grip ... to no avail. Floyd will not say how much he saw, but he acknowledges he was a witness and heard everything.

Ken Weatherwax -- who played Pugsley on "The Addams Family" TV show -- died at his home Sunday in California after having a heart attack.

Weatherwax's family tells TMZ there will be 2 funerals -- one for the family, and one for his fans.

The actor stuck with the Pugsley role over the years ... long after the original TV show went off the air in 1966. He was the voice of Pugsley in a '70s version -- and played Pugsley Sr. in an 'Addams' TV movie.

He eventually started working behind the scenes as a grip and set builder -- but he still made appearances at fan conventions.

Weatherwax was 59 years old.

2:30 PM PT -- We've learned Moseley and Hayes were married.

2:00 PM PT -- Law enforcement tells TMZ, Hayes shot Moseley and then turned the gun on himself.

"Hit the Floor" star Stephanie Moseley is dead .... after her rapper husband -- a member of Floyd Mayweather's Money Team -- shot her and then killed himself ... TMZ has learned.

We're told residents at a swanky L.A. apartment complex near The Grove heard shots ring out early Monday morning. The SWAT team raced to the scene and knocked down the door of an apartment ... and found 2 people shot to death.

The rapper Earl Hayes -- who was once signed to Mayweather's record label -- often partied with Floyd. Moseley has been a backup dancer with numerous singers, including Chris Brown and Britney Spears.

Residents heard a woman screaming in the apartment before shots rang out.

Sources connected with Moseley and Hayes tell TMZ ... he had accused her of infidelity with a famous singer.

Chris Brown just Instagrammed, "RIP baby girl. Danced with me on tour and was always the coolest person. My prayers go out to you and HAZE family."

Casey Kasem's life after death continues to be tumultuous ... American Express is gunning for more than $40K of the money he left behind.

Amex filed a creditor's claim, claiming Casey or someone in his world racked up $41,046.70.

The late DJ was in no position to use his card for more than a year before his death ... maybe more. Presumably his wife Jean used it for various purposes.

"Real Housewives of Atlanta" star Mama Joyce regrets her toxic relationship with her in-law Miss Sharon, but still ... she has no plans to go to the funeral.

Mama Joyce famously belittled her son-in-law Todd Tucker and his mom Sharon Tucker on the show ... claiming he was money hungry and Sharon was a prostitute.

But now Joyce tells TMZ she is sorry for attacking Sharon by repeating gossip (which turned out to be false) -- and wishes they'd patched things up before Miss Sharon died on Tuesday.

Silver lining? Kandi Burruss' mom says she wants to have a better relationship with Todd.

MJ added she won't attend the funeral out of respect for Miss Sharon's friends and family. She knows a lot of people would be pissed if she showed her face ... so instead she's going to send flowers.

Kandi Burruss' mother-in-law, Sharon Tucker, died in NYC Tuesday ... after suffering a stroke one day earlier.

Todd Tucker immediately flew from ATL to NY after getting the news about his mother's stroke ... according to sources close to Kandi and her husband. Todd's mom frequently appeared on "Real Housewives of Atlanta" ... and went by Miss Sharon on the show.

She slipped into a coma overnight while hospitalized after the stroke. We're told Kandi and Todd were by her side when Miss Sharon died.

The Ohio State University wrestling team has decided to pay tribute to former teammate Kosta Karageorge by putting his initials on their singlets next season ... TMZ Sports has learned.

Karageorge's body was found near the OSU campus on Sunday -- and officials says it appears he died from a self-inflicted gunshot wound. The 22-year-old wrestler and football player had a history of concussions.

We spoke with Ohio State University wrestler Josh Fox who tells us Kosta was beloved by his teammates -- which is why they've decided to put "KK" on their singlets to honor him next season.

"He was the kind of guy that if you were in a brawl, he would be the last one standing because he refused to quit or give up," Fox says.

The LAPD has submitted the Casey Kasem elder abuse investigation to the L.A. County D.A. and it targets Casey's widow Jean ... TMZ has learned.

TMZ broke the story ... an investigation was launched after Casey's kids filed a police report claiming Jean caused Casey to get bed sores that became infected and contributed to his death.

The kids claim Jean was more interested in keeping their dad from them than protecting him, which is why they say she took Casey on a wild, multi-state car ride shortly before his death.

Our law enforcement sources tell us it's unlikely the D.A. will file charges against Jean because there's not enough available evidence. The kids have been fighting for a full autopsy but Jean has resisted.

Casey's body is still rotting in Norway. It has not been buried or even embalmed.

The D.A. says it does not have the case yet, but our LAPD sources say it has been submitted.

The legendary DJ died last June.

Paul Walker fans paid tribute to the deceased actor Sunday on the one year anniversary of his death ... by appearing in droves at the site of the crash.

Hundreds huddled around the crash zone to leave flowers and pay their respects ... but the rain put a damper on candle lighting.

Walker was the passenger in a Porsche last year when the driver of the car, Roger Rodas, lost control and crashed into a tree. The car instantly burst into flames with both men inside.

Mexican President Enrique Pena Nieto tweeted, "Mexico has lost an icon whose work has transcended generations and borders."

He was 85 years old.

Fun Fact: The Bumblebee man character on "The Simpsons" was inspired by Chespirito.

"Real World" star Ryan Knight's autopsy was completed Friday morning ... and no immediate cause of death was found -- but police say he had been complaining about stomach issues.

Police in Kenosha, WI say they attempted to revive Knight when they arrived at his friends home yesterday morning ... but they were unsuccessful. They say there were no obvious signs of injuries to Knight -- but according to Knight's father he had complained about stomach issues in the past 2 days.

Cops also say no drugs were found on scene ... even though they were told he had been "partying hard" the night before.

As we previously reported ... Knight was out Wednesday night with a bunch of people and ended up at a friend's house where he was discovered dead and covered in vomit. Friends tell us he had taken "some pills" but they were not specific.

Casey Kasem wanted to be buried at Forest Lawn Cemetery in L.A. because he felt that was his path to reincarnation ... this according to his longtime friend and security guard.

Rick Hernandez says he worked as the Executive Security Officer for Casey and his family for years, and became one of the famed DJ's closest friends.

Hernandez wrote a letter to the judge in the case Casey's daughter filed to bring her dad's body back from Norway, where it's been rotting since August.

Hernandez says in the letter ... one day he asked Casey if he believed in God or the afterlife. He says Casey responded ... he believed in reincarnation. Hernandez asked if he planned to be cremated or buried, and Kasem responded that he wanted to be buried and specified Forest Lawn.

The letter wasn't enough to sway the judge, who ruled Kerri had no authority to undermine Casey's wife Jean, who has kept the body in a Norway mortuary for 3 months.

Former Washington D.C. mayor Marion Barry -- who became nationally famous after an epic cocaine bust that did not derail his career -- died Sunday morning at 78.

Barry served 4 terms as Mayor, but his defining moment for most people is what he did in a hotel room during his tenure ... smoking crack with a young woman, and as FBI barged in the room screaming, "She set me up!"

Barry -- who was a folk hero in D.C. -- became the butt of jokes and almost a staple punchline on shows like "SNL."

But after serving time for drug possession, he became mayor once again.

Barry became a paradigm of politicians … how they could do wrong, yet still remain popular with the electorate.

Cause of death has not been disclosed.

G.R.L. singer Simone Battle had just a few thousand dollars to her name when she committed suicide ... but her family claims there could be much more pouring in ... from lucrative contracts she signed shortly before her death.

Battle had just $6,000 in cash to her name when she died, according to court docs filed by her mother, Donna Morgan. But Morgan claims Battle also had deals with Sony, Coca-Cola and other companies and the estate will be getting lots of money from the deals.

Here's the problem ... Sony, Coke and the others won't give Morgan the contracts unless she's appointed administrator of Simone's estate. So she's applied, and her petition is pending.

TMZ broke the story ... Battle hanged herself in her bedroom Sept. 5th. Friends and family said she may have been depressed over money problems.
