The 49-year-old supermodel and her hubby were also joined at the event by pregnant Karolina Kurkova! Earlier in the day, Cindy signed copies of her book at Books and Books in Bal Harbour.
The day before, Cindy and Rande were seen strolling the beach together.
Cindy posted a makeup free selfie earlier in the day and people can’t stop talking about how amazing she looks in the pic!
