The American-born Princess was seen with her gorgeous, bright red hair smiling at her parents, as she celebrated her happy occasion at home in Montecito, California, with her older brother, Prince Archie. The image was accompanied by a heartfelt birthday tribute to the couple's youngest child, whom Meghan described as their "dream girl".
"Our dream girl. Happy 5th birthday, Lili [white heart emoji]," wrote Meghan.
The new picture continues a tradition the ****** ss has embraced in recent years, using birthdays and family milestones to share carefully selected snapshots of Archie and Lilibet.
While the Sussexes remain fiercely protective of their children's privacy, Meghan has increasingly offered followers glimpses into life at the family's Montecito home through her social media accounts.
Lili has clearly inherited her father, Prince Harry's, fiery red hair, and looks to be every inch her father's daughter. And, for example, we have heard her sweet American accent, know she enjoys watching Bluey cartoons, and seen the family make sweet treats for Valentine's and St Patrick's Day.
