Crawford, 51, also presented her son with a special gift, an Omega watch. The supermodel has been a spokeswoman for the company for more than 20 years.
“Big day, huge gift. Keeping @Omega in the family,” Presley captioned shots of him rocking the black watch and showing off his “Be Grateful” forearm tattoo.
Crawford posted a pic of her son crossing the stage at Malibu High School, writing, “So proud of you @PresleyGerber! Congrats on your graduation!”
Crawford and Gerber are also parents to 15-year-old model, Kaia Gerber. Kaia recently opened up to ET about how she and her mom have a lot in common.
