Who are Mariah Carey’s siblings? Meet her sister Alison and brother Morgan

Mariah Carey generally keeps her relationship with her siblings under wraps, but she’s the youngest of three.

The “Touch My Body” songstress, born in 1969, to Patricia and Alfred Carey, has an older brother, Morgan Carey, born in 1960, and and an older sister, the late Alison Carey, born in 1963.

While the pop star has had complicated relationships with her siblings over the years, she was left “heartbroken” when Alison and their mom died on the same day in August 2024.

“My heart is broken that I’ve lost my mother this past weekend,” Mariah wrote in a statement to People on Aug. 26. “Sadly, in a tragic turn of events, my sister lost her life on the same day.”

The Grammy winner didn’t disclose the pair’s causes of death but revealed she spent time with her mom before her passing at the age of 87.

However, Mariah reportedly didn’t visit or reach out to her estranged sister despite knowing Alison was in hospice care .

Mariah and her brother are the only two living members of their immediate family as their father died in July 2002 from cancer at age 72.

Mariah Carey was told estranged sister Alison was dying ‘a month ago’ — but never reached out: friend

Alison, along with Morgan and Mariah, grew up in Long Island, NY, until their parents split in 1973 when the “Fantasy” singer was 3 years old.

The pop icon and her siblings were then separated, with Mariah living with her mother while Alison and Morgan moved in with their dad.

Alison was around 14 years old when she gave birth to her first son, Shawn, in 1977, according to Us Weekly . She welcomed her second son, Michael, in 1987.

In September 2020, Mariah opened up about the disconnect between herself and her siblings after releasing her 2020 tell-all memoir about her traumatic childhood, “The Meaning of Mariah Carey.”

“We don’t even really know each other,” she told Oprah Winfrey during an Apple TV+ episode of “The Oprah Conversation.” “We didn’t grow up together … they were on their journeys.”

The “Obsessed” singer described her sister in the book as “deeply wounded” but “the most brilliant and broken person [she has] ever known,” per the US Sun .

Mariah explained Alison saw “things a child should never see,” which “damaged and derailed her girlhood.”

In April 2020, Alison filed a lawsuit against her mom , alleging Patricia allowed strangers to sexually abuse her when she was 10 years old.

Alison also claimed Patricia made her “witness adults engaged in sexual acts with both adults and children during middle-of-the-night satanic worship meetings that included ritual sacrifices.”

In her filing, Alison alleged the “post-traumatic stress disorder, anxiety and major depression” she experienced led to her drug addiction.

In her memoir, Mariah alleged Alison drugged her with Valium and “offered [her] a pinky nail full of cocaine, inflicted [her] with third-degree burns and tried to sell [her] out to a pimp” when she was around 12 and the latter was 20.

In February 2021, Alison denied the allegations and sued Mariah for defamation.

Alison and Mariah have remained distant over the years and the “We Belong Together” singer never visited her sister when she was admitted to a mental hospital in New York in 2012, per the Daily Mail .

At the time, Morgan called out Mariah for “not [finding] it in her heart to help Alison get the care she requires,” according to the outlet.

“The worst is yet to come and Mariah has it in her power to at least ensure a soft landing and avoid a life time of regret about missing this opportunity to forgive and help her only sister,” he told the outlet.

“Mariah is the one person in the family who could actually make a real meaningful difference to Alison’s life.”

Alison was on hospice care for three weeks before she died in Greene County, NY, at the age of 63 the weekend of Aug. 24, 2024, per the Times Union .

Her close friend, Dave Baker, told the US Sun that she held a “tough exterior” but was a “highly intelligent, warm and sensitive person.”

Morgan grew up to have careers as a music producer, celebrity fitness trainer and fitness model.

“He was strikingly handsome and occasionally worked as a model,” Mariah wrote in her book. “He was well known and well liked.”

Mariah explained her big brother gave her $5,000 to release her self-titled debut album in 1990, though she later paid him back.

The brother-sister duo have been estranged since 1994 when they got into a big argument, per the Daily Mail . Their feud heightened after Mariah claimed her brother was violent in her memoir.

Mariah alleged Morgan once “slammed” their mom Patricia “so hard” into a wall, creating a noise similar to a gunshot.

“Next thing I knew she was totally limp, as if her bones had melted, folding onto the floor,” she wrote in her book.

“It was a split second. It was an eternity. My eyes were still fixed in place, only now I was looking at my mother collapsed in a crumpled pile on the floor.”

The producer also allegedly got into an altercation with his father, prompting about a dozen law enforcement officers to intervene.

Mariah also accused her brother of being a drug dealer when he worked at bars in New York City in the 1980s.

“He discreetly supplied the beautiful people with their powdered party favors. He was diabolically charismatic,” she wrote.

In 2021, Morgan sued Mariah for writing “false and defamatory” passages about him that were “personally invasive and painful” and caused “serious damage to his reputation and to his personal and business affairs.”

Morgan, who lived in Italy at the time with his, wife Ilaria Negrini Carey, claimed he lost a deal on a massive film project due to the pop icon’s bombshell memoir.

Morgan denied being violent and alleged his father was the abuser.

He also slammed his sister for portraying him in a negative light instead of highlighting his journey to overcoming his cerebral palsy and grand mal epilepsy.
