Billie Lourd, the daughter of Carrie Fisher and granddaughter of Debbie Reynolds, penned a heartfelt tribute to the two actresses on her Instagram Monday, her first public statement since Fisher and Reynolds died on consecutive days in late December.

"Receiving all of your prayers and kind words over the past week has given me strength during a time I thought strength could not exist," Lourd wrote in the caption alongside an undated family photo of her, Fisher and Reynolds.

"There are no words to express how much I will miss my Abadaba and my one and only Momby. Your love and support means the world to me."

On Friday, it was revealed that Fisher and Reynolds would be buried together at Hollywood Hills' Forest Lawn Memorial Park following a private joint funeral service.

Fisher's Star Wars co-star Mark Hamill, who previously remembered the actress on Facebook, penned a longer tribute for The Hollywood Reporter Monday.

"Carrie and I occupied a unique area in each other's lives. It was like we were in a garage band together that somehow hit it huge. We had no idea the impact Star Wars would have on the world," the actor wrote in the remembrance.

"Part of what was so poignant about her was that she was vulnerable, that there was this glimmer of a little girl that was so appealing and it roused the protective nature in my personality. I'm grateful that we stayed friends and got to have this second act with the new movies. I think it was reassuring to her that I was there, the same person, that she could trust me, as critical as we could sometimes be with each other. We ran the gamut over the years, where we were in love with each other, where we hated each other’s guts. 'I'm not speaking to you, you're such a judgmental, royal brat!' We went through it all. It's like we were a family."
