The 60-year-old passed away a day before her own mother, Debbie Reynolds, who died aged 84. According to her death certificate, the Singin' In The Rain star died from a blood vessel that ruptured and caused bleeding in her brain. Her official cause of death is listed as an intracerebral haemorrhage. The following day, mother and daughter were laid to rest together at Forest Lawn Memorial Park in Los Angeles. Debbie was buried with some of Carrie's ashes, which were in an urn shaped like a Prozac pill.
Back in December, the new mum shared a loving picture of her as a child alongside her mother and grandmother.

"Happy holidays! (But also sad/emotional/weird/stressful holidays!) Sending my love to everyone who has lost someone they loved and is missing them a little extra today.
"I see you. It's okay if everything ain't all merry and bright. It can be a mix of all of it. And it's all okay. Feel all the feelings - the good and the not so good. Eat something delish they used to love. Put on one of their favorite songs. Tell a story about them. Cry about them. Call one of their friends you haven't talked to in a while. Be kind and patient with yourself. Don't grieve in silence. You're not alone.," she wrote alongside it.
