The 55-year-old pop superstar was left devastated after Alison, 63, and her mother Patricia, 87, passed away on the same day over the weekend (24-25.08.24) but Mariah had not spoken to her sibling in a long time due to issues over her drug problems and now it's been revealed Alison had been hoping to make up while she was being cared for in a hospice at the end of her life.
Alison's friend and healthcare provider David Baker, told DailyMail "I know it was her dying wish if she could've at least had a conversation with Mariah ... "
Mariah previously opened up about her troubled relationship with Alison in her 2020 memoir 'The Meaning of Mariah Carey', claiming she had long struggled with drug addiction and the singer decided to cut contact with her "ex-sister".
Baker added of the book: "It stung because Mariah called Alison her ex-sister. [Alison] used to babysit and take care of Mariah. When that came out, she couldn't believe that Mariah had done that because she already was not talking to her, but then she kicks Alison in the teeth while she was already down."
After the double tragedy, Mariah shared her sorrow in a statement which read: "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.
"I feel blessed that I was able to spend the last week with my mom before she passed. I appreciate everyone's love and support and respect for my privacy during this impossible time."
In her book, Mariah revealed she had decided to cut ties with both her sister Alison and her brother Morgan Carey, 64, following extensive therapy.
She wrote: "For my sanity and peace of mind, my therapist encouraged me to literally rename and reframe my family ... Morgan my ex-brother and Alison my ex-sister...
"I had to stop expecting them to one day miraculously become the ... big brother and big sister I fantasised about.
"I had to stop making myself available to be hurt by them. It has been helpful. I have no doubt it is emotionally and physically safer for me not to have any contact with my ex-brother and ex-sister."
