Carrie Fisher's friends and family are coming together to mourn the late actress.

A private memorial for the Star Wars star was held on Thursday at her home in Beverly Hills, California, with Meryl Streep, Gwyneth Paltrow, Meg Ryan, Courtney Love, Ed Begley Jr. and Ellen Barkin in attendance alongside Fisher's brother, Todd Fisher, and his wife. Fisher's daughter, Billie Lourd, was joined by her Scream Queens co-star, Taylor Lautner.

Streep was among the first to arrive with an arrangement of white flowers in tow. Fisher's beloved dog, Gary, was also on hand as guests arrived.

As ET previously reported, Fisher, 60, was cremated earlier this week following her Dec. 27 death, after going into cardiac arrest aboard a Los Angeles-bound flight from London. At this time, Fisher's autopsy report has been placed on a security hold.

Just one day after Fisher's untimely death, her mother, Singing in the Rain actress Debbie Reynolds, also died from a suspected stroke at 84 years old. She will be laid to rest on Friday, according to a source, and some of Fisher's ashes will be buried with her. Also on Friday, Broadway will dim its lights at 7:45 p.m. ET in honor of the actresses.

The source also tells ET that a public memorial for both actresses is being planned for months down the road. Among those expected to attend are Streep, Tom Hanks, and even Fisher's ex-husband, Paul Simon, though details have not yet been finalized.
