The 13-year-old who had inherited her dad's knack for shooting hoops is seen in high heels and a dress in a training session alongside other players in full kit.
The tragic teenager, who died alongside NBA All-Star and Olympic gold medalist Bryant in a helicopter crash on Sunday morning, is seen scoring hoops and then dribbling the ball.
The footage was shared on Instagram in the hours of the crash and showcases her natural talent, as she casually loops the ball back and forth between her legs.
Other players are seen in the background running training drills around cones as coaches watch on.
As well as Bryant and Gianna, known as GiGi, four other victims of the crash - which killed a total of nine - have been named.
