The 24-year-old Scream Queens star captioned the super sweet flashback photo with a simple heart emoji.

This is Lourd's first Mother's Day without Fisher, who died in December, several days after undergoing cardiac arrest.

Lourd also lost her grandmother, Oscar winner Debbie Reynolds, who died of a stroke one day after Fisher died.

Earlier this month, the actress shared another touching throwback photo of her and her mother in celebration of Star Wars Day. The sweet photo showed Fisher holding her little girl in her arms as they walked alongside Chewbacca.
