"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 said in an Instagram post Monday. "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."
The message accompanied a sweet family photo of Lourd as a little girl with her mom and grandmother.
Fisher died Tuesday at the age of 60 after suffering a mid-flight heart attack on Dec. 23. Reynolds, 84, had a stroke and died a day after Fisher passed. Lourd, 24, is Fisher's only child.
