LOS ANGELES — Mariah Carey’s mother Patricia and her sister Alison died on the same day, the singer said Monday.

“I am heartbroken to have lost my mother this past weekend. Unfortunately, in a tragic turn of events, my sister also lost her life that same day,” the Grammy winner said in a statement.

“I feel blessed to have been able to spend the last week with my mother before she passed away,” the statement continued. “I am grateful for everyone’s love and support and respect for my privacy during this impossible time.”

Further details about the cause of death were not immediately available. People Magazine first reported the death news and Carey’s statement.

Patricia was an opera singer and was previously married to Alfred Roy Carey, the singer’s father. The parents divorced when the “Obsessed” singer was 3 years old.

Carey detailed her complicated relationship with her mother and sister in her 2020 memoir, The Meaning of Mariah Carey. She wrote that she and her mother often clashed and blamed her sister for putting her in unsafe situations as a child.

Nevertheless, Carey stayed in touch with her mother and even recorded a duet of “O Come All Ye Faithful/Hallelujah Chorus” for the singer’s second Christmas album in 2010.
