One week after sharing a throwback photo of her late mother, Carrie Fisher and late grandmother, Debbie Reynolds, Billie Lourd took to Instagram again with another picture and emotional tribute to her mom.

Last week, Lourd posted a photo of the actresses and thanked fans for all their love and condolences during such an extremely difficult time.

"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," she captioned the shot of the three of them together. "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 Wednesday, Jan. 11, she shared another pic of Fisher with a heartfelt tribute writing, "Finding the funny might take a while but I learned from the best and her voice will forever be in my head and in my heart."

As we reported. while Lourd and her family were mourning the sudden death of Fisher, Reynolds passed away from a stroke just one day after her daughter died.
