Mariah Carey’s mother Patricia and sister Alison passed away on the same day last weekend.

“I am heartbroken that I lost my mother this past weekend. Sadly, in a tragic turn of events, my sister lost her life on the same day,” the 55-year-old singer said People.

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

Neither the date of death nor the cause of death of Patricia and Alison were mentioned.

In her 2020 memoir The Meaning of Mariah Careythe star shared how her therapist once advised her to redefine her relationship with her family for her own “sanity and peace of mind.” Reflecting on this period in her life, Carey wrote, “My mom became Pat to me, Morgan became my ex-brother, and Alison became my ex-sister… I had to stop expecting them to one day miraculously become the mom, big brother, and big sister I fantasized about.”

The singer also opened up about her difficult relationship with her mother, who had been a “cloud of sadness” her entire life. “Our story is a story of betrayal and beauty. Of love and abandonment. Of sacrifice and survival,” Mariah recalled. “I’ve freed myself from slavery multiple times, but there’s a cloud of sadness that I suspect will always hang over me, not just because of my mother, but because of our complicated journey together.”

The Grammy winner described their bond as complex and deep: “Ours is a thorny cord of pride, pain, shame, gratitude, jealousy, admiration and disappointment. A complicated love connects my heart to my mother’s.”
