Billie Lourd

The Scream Queens star posted a touching throwback photo on Wednesday, showing her as a little girl, wearing bunny ears, sitting in the back of a limo with her famous mom.

"'If my life weren't funny then it would just be true and that is unacceptable,'" Lourd wrote, quoting Fisher, and attributing the quote with the same wingdings-like characters that the Star Wars icon used in most of her Twitter posts.

"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," Lourd added.

Fisher died on Dec. 27,
days after going into cardiac arrest during a flight from London to Los Angeles International Airport. Fisher's mother, screen legend Debbie Reynolds, died the following day as a result of a stroke.

Earlier this month, Lourd broke her silence about losing both her mother and grandmother with another emotional family photo of all three generations of actress.

"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. Watch the video below for more on her powerful tribute.
