A birthday at the beach is a birthday well spent.

Christie Brinkley hit the beach in Turks and Caicos with daughter Alexa Ray Joel to celebrate Joel’s 29th birthday on Monday. The 60-year-old supermodel and the birthday girl posed for a photo in their bikinis, which was then posted to Brinkley’s Instagram with the caption: “Having Fun in the Sun with our Birthday Girl Alexa Ray! Happy Birthday.”
