Mariah Carey's Mother and Sister Pass Away

Pop star Mariah Carey's mother and sister tragically pass away on the same day...

From TMZ

The singer said in a statement to TMZ, "My heart is broken that I’ve lost my mother this past weekend. Sadly, in a tragic turn of events, my sister lost her life on the same day."

Mariah added, "I feel blessed that I was able to spend the last week with my mom before she passed."

She wrapped the message, "I appreciate everyone’s love and support and respect for my privacy during this impossible time."

Patricia and Alison's causes of death are not known at this time.

Mariah's relationship with her mom was pretty complicated ... describing it as a "prickly rope of pride, pain, shame, gratitude, jealousy, admiration, and disappointment" in her 2020 memoir, "The Meaning of Mariah Carey."

Even with their rocky relationship, Mariah and her mom maintained their bond ... and she even dedicated part of her memoir to her, saying her mom did the best she could and that she’d always love her as best as she could.

Mariah's relationship with her estranged sister was even more tangled -- and Alison even sued Mariah her famous siter over abuse claims from her memoir.
