The two had a blast at the ultra-exclusive Hotel du Cap-Eden-Roc on a trip to Cap D'Antibes and St. Tropez on Sunday.
The Sports Illustrated model stunned in an orange bikini as she balanced on a swing above sea level.
She also struck some expert model poses while high up. Potential photo shoot perhaps?
Christie, who turned 64 in February, looked equally as stunning in her all-white bikini as she made her way out of the water.
The former supermodel sported the same color for a Bella New York Magazine party back in late May that featured her other daughter, Alexa Ray Joel, on the cover.
