Billie Lourd shared an old family photo with her late mother, Carrie Fisher, to Instagram Wednesday night. The 24-year-old actress posted a flashback photo of her as a child sitting in the lap of her mom while in a stretch limo. Lourd captioned the image with twinkle stars and an angel emoji. The photo tribute comes nearly two months after Fisher Lourd's grandmother, Debbie Reynolds, died within days of one another.
