Age ain’t nothing but a number for Cindy Crawford.

On Sunday, husband Rande Gerber shared a sultry snap of the legendary supermodel in a tiny two-piece while vacationing in the Bahamas.

“Rande caught me in the blue lagoon,” the 50-year-old bombshell shared on Instagram, in addition to thanking Gerber, 53, for capturing the sexy Kodak moment.

While Crawford and Gerber have been documenting their tropical getaway on social media, this trip isn’t for couples only. The businessman also posted a sweet photo of daughter Kaia Gerber, 14, as they enjoyed a quaint lunch date.

The Gerber clan have been doing quite a bit of traveling to ring in Crawford’s 50th year. Following a birthday celebration south of the border, Crawford and her spouse of nearly 18 years jetted to St. Barts.
