"Nobody told me what happens on this ride," Bella wrote, captioning a picture of the sisters and friends on the Tower of Terror ride. "Luiz had the best day of his life. Gigi wore Mickey gloves for six hours."
Gigi, 21, shared a snap of her and Bella, 20, with the Mouse himself.
The sisters are in France ahead of Paris Fashion Week, which begins on Tuesday. They have already been slaying the runways during New York and London fashion weeks earlier this month. Check out some of Bella's best looks in this video.
