The special meaning behind the urn that holds Carrie Fisher and Debbie Reynolds' ashes.

Carrie Fisher’s loved ones have gathered to farewell the Star Wars actress at a private memorial at her Beverly Hills home.

Fisher died aged 60 on December 27 following a heart attack. Her 84-year-old mother, fellow Hollywood icon Debbie Reynolds, died a day later after a possible stroke.

Among the 125 friends and family who attended the emotional day were celebrities Meryl Streep, Meg Ryan, Gwyneth Paltrow and George Lucas, as well as close relatives including daughter Billie Lourd and brother Todd Fisher.

In one special moment, Streep, 67, performed a rendition of Fisher’s favourite song, Happy Days Are Here Again after delivering a eulogy. The song was originally recorded in 1929.

"By the end, everyone was singing," a family friend told People.

A source said Lourd wanted those her mother loved to be together in her living room one final time.

Mourners were served the same food Fisher would offer at her famous parties: fried chicken, collard greens, cornbread.

“The only things missing were Carrie and Debbie,” says the friend.

A funeral for Reynolds was held a day after Fisher's intimate memorial. It has been reported their ashes have been safeguarded together in a urn shaped like a giant Prozac pill.

Fisher's brother Todd explained the choice: "Carrie's favourite possession was a giant Prozac pill that she bought many years ago. A big pill."

"She loved it, and it was in her house, and Billie and I felt it was there she'd want to be," he told Entertainment Tonight.

Todd said when choosing how to lay his mother and sister to rest, they "couldn't find anything appropriate". He added that "Carrie would like" the pill idea.

"It was her favourite thing, and so that's how you do it. And so they're together, and they will be together here and in heaven, and we're OK with that," he said.

RIP Debbie and Carrie.
