The 15-time Grammy-winner turned the big 4-0 on Monday and joyfully celebrated the milestone with her husband, Swizz Beatz (né Kasseem Dean) during a tropical weekend getaway.

The pair, along with several loved ones, seemingly enjoyed a lavish, beachside dinner complete with live music and a firework display ahead of her big day.

In an instagram post he shared on Sunday, Beatz, 42, wrote a heartwarming message admiring his wife.

Keys appeared to be having the time of her life as she happily danced along the beach in a gorgeous, flowing dress.

The " Falling " hitmaker and Beatz appeared happy as can be en route to the special celebration.

In 2003, Keys co-founded Keep a Child Alive , a nonprofit organization which began as an emergency response service and has a mission to improve the health and wellbeing of those in need, worldwide.
