According to People magazine, the service of remembrance will be "ultra-private", and will take place at the pair's Beverly Hills compound where they were next-door neighbours.
The funeral of the iconic mother-daughter pair, who died just one day apart from each other in December, has been planned by Debbie's son, Todd Fisher, and Carrie's daughter, Billie Lourd. Todd spoke about making the arrangements to New York Daily News, saying: "It's what we want to do, but we're still working on the mechanics. I'm going out right now to look at places. We like the idea, if it's at all possible. I think it's appropriate." He added to Good Morning America: "Carrie loves a good party, so, you know, I'm sure she'll want to throw a party for her."
He also spoke about how he was sitting with his mother on the day she died, just 24 hours after Carrie passed away. He told ABC News: "She was very peaceful and quiet. It happened very gently. She loved taking care of my sister more than anything. So, she gets to do that and that's what she wanted to do."
With the Golden Globes fast approaching, the award ceremony's executive producer Barry Adelman has confirmed that they are planning to pay tribute to the two actresses, saying: "We've always kept the show as a celebration and as a party, and yet we realize this is a special circumstance — certainly with the recent passings of Carrie Fisher and Debbie Reynolds. So we're going to acknowledge it, but we're still in discussion with exactly how we're going to do that."
