Jewel sends fans in a frenzy with stunning bikini snaps as they ask singer if she drank 'youth serum'

Jewel is bringing the heat to the holiday season.

In a recent Instagram post, the 51-year-old country singer shared a few bikini photos from her vacation to the Caribbean island, Barbuda, captioning the post, "#Barbuda for a few days of sun before more winter snow."

The first photo in the slideshow featured Jewel smiling at the camera with the wind blowing her hair back, as she stood on the beach in an animal-print bikini. The ocean waves can be seen crashing onto the shore behind her.
