Elizabeth Hurley is fifty and fabulous. The Royals actress took to her Instagram account to show off her age-defying bikini body while vacationing with her handsome son Damian, and it's safe to say she looks incredible.

"Mellow in yellow," Hurley wrote alongside a photo of her looking relaxed as she poses next to a palm tree in a bright bikini from her swimwear line (below).

If you love her swimsuit, you're in luck. The sexy neon two-piece is currently available for $202 at (Fabulous figure not included.)

The British beauty, who is on a break from filming season two of The Royals, is using her vacation as an opportunity to promote her line, as well as show off her fabulous off-duty style. See what else she's posted from paradise below.
