Billie Lourd posts tribute to mum Carrie Fisher: 'Finding the funny might take a while'

Billie Lourd has shared her second Instagram post following the tragic deaths of her mum Carrie Fisher and grandmother Debbie Reynolds.

The 24-year-old Scream Queens star posted a sweet throwback photo for her 700k followers and captioned the shot with a quote from Carrie.

"If my life weren't funny then it would just be true and that is unacceptable," she quoted, then added, "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."

The only daughter of Carrie and Eddie Fisher, Billie had a bit role alongside her mother in 2015's The Force Awakens, and the mother-daughter duo will also appear in this year's Star Wars: Episode VIII, which was completed before Carrie's death.

"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," Billie, who is dating her Scream Queens co-star Taylor Lautner, captioned a January 3 Instagram. 

"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."

Carrie Fisher passed away from a heart attack at age 60 on December 27. Debbie Reynolds, 84, suffered a stroke just one day later and passed, as well.

According to Carrie's brother Todd, Debbie's last words were, "I want to be with Carrie."
