RIP

Lee Thompson Young's suicide is a dark mystery ... because law enforcement sources tell TMZ he did NOT leave a suicide note.

TMZ broke the story ... Young was found dead in his North Hollywood apartment Monday. We're told he died from a self-inflicted gunshot wound.

Our sources say Young did have a diary ... but we're told none of the entries reveal why he would have taken his life ... at least at first glance.

Law enforcement sources also tell TMZ ... Young was last seen on Saturday and they believe he may have taken his life sometime that day.

The case is a real mystery because everyone we've spoken with in Young's life tells us he had no apparent serious life issues.

Lee Thompson Young -- who played the main character on Disney's "The Famous Jett Jackson" -- has committed suicide, TMZ has learned. He was 29.

Young's body was discovered inside his North Hollywood home Monday with a self-inflicted gunshot wound, according to sources. It's unclear why Young took his own life.

Lee's publicist said, "It is with great sadness that I announce that Lee Thompson Young tragically took his own life this morning ... Lee was more than just a brilliant young actor, he was a wonderful and gentle soul who will be truly missed."

Young currently appears in the TNT show "Rizzoli & Isles" -- and we're told when he didn't show up to work Monday morning, staffers called Young's landlord to check up on the actor. That's when the landlord found him.

The executive producer of "Rizzoli & Isles" tells us, "Everyone at [the show] is devastated by the news of the passing of Lee Thompson Young."

She adds, "We are beyond heartbroken at the loss of this sweet, gentle, good-hearted, intelligent man. He was truly a member of our family. Lee will be cherished and remembered by all who knew and loved him, both on- and offscreen, for his positive energy, infectious smile and soulful grace. We send our deepest condolences and thoughts to his family, to his friends and, most especially, to his beloved mother."

Young was a rising star in Hollywood. After he made it big as a Disney star, he went on to play running back Chris Comer in the 2004 movie "Friday Night Lights."

Some of Gia Allemand's closest friends and co-workers came together at the Mississippi River this weekend to pray for the reality star in an emotional farewell ceremony.

More then 50 people, wearing white ribbons, tossed white flowers into the water to "symbolize that our love and memory of [Gia] will continue to flow in our hearts."

Gia passed away on August 14, two days after she attempted suicide in her New Orleans home.

Allemand will be laid to rest on Thursday following a funeral ceremony at Trinity Grace Church in Chelsea, NY.

Gia Allemand -- the former "Bachelor" contestant who hanged herself this week -- had tweeted about suicide for nearly a year, describing the unbearable pain of being bullied -- something she experienced first hand.

TMZ has poured over Gia's tweets, and we found this:

-- October 11, 2012. Gia re-tweeted, "Words Hurt. Pain Lasts. And suicide last forever." The tweet referenced a 16-year-old Canadian girl -- Amanda Todd -- who hanged herself earlier that year after being bullied.

-- Ocober 13, 2012 Gia tweeted, "BULLYS YOU SUCK RT ... Amanda she committed suicide because of bullying:' ( "

Gia was very sensitive to bullying:

-- October 11, 2011, she tweeted, "As a victim of being bullied most of my life, I'm gonna say that people who can say mean things to other people and put them down are just insecure and depressed with their own life! Glad my momma always told me 'if you don't have something nice to say than don't say it."

Lisa Robin Kelly's autopsy is complete ... but cause of death is still unknown, TMZ has learned.

A spokesperson for the L.A. County Coroner's Office tells TMZ, the autopsy was finished Saturday -- but the cause of Lisa's death won't be known until the toxicology results are in ... which could take weeks.

NBA star Ryan Anderson is going through HELL right now following the suicide of GF Gia Allemand ... so says his ex-teammate Greivis Vasquez, telling our camera guy, Ryan needs his team more than ever right now.

The Sacramento Kings star knows Ryan from their days on the New Orleans Hornets (now Pelicans) -- and knew Gia very well from the 2 years she and Ryan dated. Of her death he says, "It's really tough. There are no words."

Vasquez says the toll it's taking on Ryan (who found her body) is painful to see. He explains, "It's just hard. I know he's feeling guilty." Adding, "We gotta support him. We gotta be there for him." He goes on.

More fingerpointing in the death of "That '70s Show" star Lisa Robin Kelly ... 'cause after Kelly's boyfriend blamed her estranged husband for causing the actress to relapse ... the husband tells TMZ the fault lies with the BF.

We spoke with Kelly's estranged husband Robert Gilliam ... who tells us the only reason LRK's boyfriend trashed him to the media after she died Thursday is because "he's trying to cover his own ass."

"In the last two weeks, she called me 22 times to get away from him," Gilliam says.

Gilliam says he offered to help Lisa -- who struggled with alcohol abuse for years -- but under one condition ... she had to check in to a rehab center closer to Northe Carolina, where they lived when they were together.

Gilliam says Lisa agreed -- so he started setting things up ... but she passed away before she could make the move.

August Schellenberg -- who played Jesse's Native American mentor in "Free Willy" -- has died Thursday in Texas after a long battle with cancer ... TMZ has learned.

Schellenberg's family tells TMZ ... August died peacefully surrounded by loved ones.

77-year-old Schellenberg had a long and storied career in Hollywood -- often playing Native American characters.

In fact, he was nominated for an Emmy for Best Supporting Actor in a Miniseries or Movie for his role as Chief Sitting Bull in "Bury My Heart at Wounded Knee."

August appeared in all 3 "Free Willy" movies. He also appeared alongside Christian Bale and Colin Farrell in the 2005 flick, "The New World."

Story developing ...

Lisa Robin Kelly was not taking any withdrawal drugs at the time she died -- at least that's what the rehab facility told law enforcement ... TMZ has learned.

Our law enforcement sources tell us ... reps from the L.A. County Coroner and L.A. County Sheriff's homicide came to Pax Rehab House in Altadena, CA Thursday afternoon, and officials from Pax said unequivocally ... they did NOT give Lisa any drugs.

TMZ broke the story ... the star of "That '70s Show" died in her sleep Wednesday night, after being admitted to the facility on Monday for alcohol abuse.

We're told law enforcement is calling Lisa's death "a mystery." There were no drugs or alcohol in her room, no vomit in her airway, and no obvious sign of trauma.

As we reported ... Lisa's boyfriend took her to the hospital Sunday, where she registered a .34 blood alcohol level, which is borderline fatal. Lisa was admitted to Pax the next day, and she had been to rehab dozens of times before -- yes, dozens.

The Coroner is doing an autopsy.

Gia Allemand turned to the church just one day before her suicide ... paying close attention to the service and even taking notes during the pastor's sermon, TMZ has learned.

Sources close to the former "Bachelor" star tell TMZ ... Gia was a practicing Christian and attended a Sunday service at her local New Orleans church on August 11.

One source close to Gia tells us the reality had been struggling recently ... "She was a Christian, but couldn't be fulfilled. She thought the world expected more from her. She put so much pressure on herself and couldn't see the love around her."

We're told Gia had been venting about her relationship with NBA player Ryan Anderson in the weeks before her death, but Gia's concerns were pretty ordinary for a couple that had been dating for more than 2 years.

Hours before she attempted to take her own life, we're told Gia went about her daily routine as if nothing was wrong ... even teaching a 1:30 pm class at an exercise studio on August 12.

Later that night, Gia's boyfriend discovered the reality star in her home after she had hanged herself. She passed away two days later.

Lisa Robin Kelly -- who played Eric Forman's older sister on "That '70s Show" -- has died ... TMZ has learned.

The 43-year-old actress passed away in her sleep Wednesday night at a rehab facility in California.

We spoke with Kelly's agent who tells us the actress had just voluntarily checked herself in for treatment for an alcohol problem this past week ... and was determined to clean herself up.

The agent tells us, "She had been fighting demons for a while and finally lost her battle."

Sources tell us Lisa had been in and out of rehab centers hoping to kick her alcohol problem ... and most recently fell off the wagon after a huge dispute with her estranged husband Robert Gilliam.

Sources say ... Kelly's estranged husband beat her last May to obtain residual money from her show. He was convicted of domestic battery last month and sentenced to 3 years probation. He also served 35 days in jail for the beating.

Lisa filed for divorce from Gilliam back in July.

We're told Lisa's new boyfriend brought her to rehab again on Monday ... but she went into cardiac arrest late Wednesday night and could not be saved.

The boyfriend blames her estranged husband for the relapse.

Sources connected with the attempted rescue tell TMZ ... when emergency responders arrived at the rehab facility, they found needle marks on both of Lisa's arms.

However, her BF tells us the reason for the needle marks is that he took Lisa to a hospital on Sunday -- because she had a .34 blood alcohol level ... and nurses made multiple attempts to insert a needle into her vein to extract blood.

After several attempts, medical personnel were able to use a vein on the top of Lisa's wrist.

Kelly had been troubled for the past couple of years -- she was arrested at least 4 times in the past 3 years for DUI, spousal abuse and assault.

Besides "That '70s Show," Kelly had appeared in several TV shows and movies including "Amityville Dollhouse."

Paris Jackson lost her soul when her father died ... so said Michael Jackson's ex-wife Debbie Rowe on the stand today, breaking down into tears.

Debbie was testifying for AEG in the wrongful death lawsuit Thursday, when the subject turned to MJ's 15-year-old daughter and her recent suicide attempt.

Debbie said she had been in touch with Paris every day until June 5, when paramedics were called to the Jackson mansion in Calabasas after Paris downed a bunch of Motrin and cut herself with a butcher's knife.

Debbie said Paris had been "devastated" by her father's death and that's what caused the suicide attempt. Debbie added, "She tried to kill herself ... She has no life. She doesn't feel she has a life anymore."

Paris is currently at an undisclosed residential treatment center outside California.

TMZ has obtained the 911 call placed moments after "Bachelor" star Gia Allemand's boyfriend Ryan Anderson found her on Monday, following an apparent suicide attempt -- in which you can hear what sounds like Ryan saying "don't stop" giving CPR.

The audio is choppy, but from what you can hear the dispatcher gives CPR instructions to Ryan. It sounds like Ryan then relays those instructions to someone else -- presumably Gia's mother who was present -- telling her, "Keep going ... don't stop." Ryan sounds calm.

As we reported, Gia's cause of death is suicide. She was hospitalized in New Orleans after Ryan found her in her room, and she was subsequently placed on life support. Gia died on Wednesday.

Ryan -- who plays basketball for the New Orleans Pelicans -- was by Gia's side when she died, along with Gia's mother.

Gia appeared on Season 14 of the reality show. She was 29.

Michael Jackson's ex-wife Debbie Rowe just arrived at court to testify in the wrongful death lawsuit -- but even though she's testifying for AEG, her brief statement this morning makes it sound like she might secretly be playing for the other team.

As we reported, Debbie views herself as a hostile witness because she believes AEG is largely responsible for Michael's death -- but the fact is ... our sources say Debbie thinks a lot of Michael's doctors share the blame.

Rowe's testimony is significant because AEG is trying to show MJ misused Propofol for years -- thanks to diabolical drug-pumping doctors -- and engineered his own demise ... but if she takes a left turn and says AEG pushed MJ over the edge, it's bad news bears.

2:13 PM PT -- TMZ has learned Gia hanged herself. Her boyfriend, Ryan, found her hanging and unconscious in her home and immediately called 911.

1:17 PM PT -- TMZ has learned ... the cause of death was suicide. Gia's boyfriend Ryan Anderson found Gia in her house Monday night. We're told Gia was on life support, which was withdrawn today. She had suffered "critical loss of brain and organ function." Her mom, boyfriend and other friends were in the hospital when she died.

1:13 PM PT -- Although we do not know the cause of death yet, we were told by multiple people close to Gia that she had been extremely upset about a rocky relationship with her boyfriend Ryan Anderson.

"Bachelor" star Gia Allemand -- who appeared on Season 14 of the show -- is dead, a family member tells TMZ.

As we reported, the 29-year-old model had been hospitalized in New Orleans since Monday following what her family called a serious emergency medical event. The details surrounding the event are unclear, but it was announced that Allemand had been placed on life support.

Allemand's mother and longtime boyfriend NBA player Ryan Anderson -- of the New Orleans Pelicans -- were at her side when she died.

Season 14 winner Vienna Girardi tells us, "Gia was a beautiful girl and an unbelievable friend. I’m shocked and can’t believe what happened to her. She seemed so happy, but you never know the demons people are fighting inside. I will never forget her and will miss my friend forever."

Allemand's boyfriend, Ryan Anderson, has released a statement ... saying, "I'm deeply grateful for all the love and support we have received from family, friends and fans. Gia was the most beautiful person I knew inside and out and she always smiled and made everyone else around her smile."

He continues, "She had such an amazing impact on my life and anyone that knew her was blessed. All I have left is to cherish those memories we made together and help perpetuate the many values, faith and love that we shared."

Michael Jackson's ex-wife Debbie Rowe just broke down in tears while testifying in the MJ wrongful death trial, claiming the singer's doctors held a "pissing match" to outdo each other by giving Jackson the "better" drugs ... a competition that fueled his deadly drug addiction.

On the stand, Rowe pointed the finger at two doctors specifically -- Dr. Arnie Klein and Dr. Steven Hoefflin -- claiming MJ trusted them to prescribe his pain medication, and they consistently tried to one-up the other by giving MJ increasingly stronger doses of painkillers.

Rowe said Dr. Conrad Murray then "got in there and killed him." She added, "I was probably one of the only ones who said no to MJ."

Rowe said MJ had a notoriously low tolerance for pain, which paved the way for the abuse of painkillers like Demerol and Diprivan.

Rowe called Klein and Hoefflin idiots for going back and forth at the same time, trying to outdo each other and not looking out for MJ's best interest.
