The couple divorced when the singer was three years old.
Carey has spoken in the past of her complicated relationship with her mother and siblings, writing in her 2020 memoir The Meaning of Mariah Carey that it was “emotionally and physically safer for me not to have any contact” with Alison or Morgan.
She described her relationship with her mother as a “prickly rope of pride, pain, shame, gratitude, jealousy, admiration and disappointment”.
“Like many aspects of my life, my journey with my mother has been full of contradictions and competing realities,” Carey wrote. “It’s never been only black-and-white — it’s been a whole rainbow of emotions.”
She added: “A complicated love tethers my heart to my mother’s.”
Despite the tumultuous relationship, the pair maintained contact and even recorded a duet of O Come All Ye Faithful/Hallelujah Chorus on a Christmas album in 2010.
Carey has said her mother was the inspiration for her becoming a professional singer.
“I would sing little tunes around the house, to my mother’s delight. And she always encouraged me,” she wrote in her memoir.
