“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 a throwback photo of herself with 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.”

The two actors passed away within one day of each other, with Fisher, 60, dying Dec. 27 after suffering a heart attack on Dec. 23 and Reynolds, 84, of a stroke on Dec. 28.
