Kaia Gerber spent time with her mother, Cindy Crawford, in Malibu on Saturday afternoon. The 20-year-old fashion industry personality and the 56-year-old supermodel were seen putting gas into their car at a picturesque rest strop in the area. Crawford shares her daughter, as well as 23-year-old son Presley, with her husband of over two decades, Rande Gerber.
