Jewel fans can't help but gush over the singer's sexy swimuits

Jewel isn't playing any foolish games when it comes to her choice of swimwear.

Last month, the singer-songwriter, 49, hosted a tennis fundraiser event for her Inspiring Children Foundation on Necker Island in the Caribbean.

A photo slideshow shared to her Instagram on Nov. 28 showed a behind-the-scenes look at the Grammy winner's trip — and her impressive bathing suit collection.

Jewel's swimsuit moments included a plunging black hi-rise one-piece, as well as a maroon V-neck suit she wore while spending time on the beach with her 12-year-old son Kase, whom she shares with her ex-husband, Ty Murray.

She later teamed the red suit with a long-sleeve floral rash-guard swim top to explore sea caves with her teen.

Fans couldn’t help but swoon over Jewel’s effortless beauty and bombshell physique.

“How are you aging backwards?” one user commented.

“Jewel not only are you a talented singer, with a beautiful heart, but also your one hot looking mama,” gushed another.

Jewel’s Instagram video also included vacation-type snapshots of the tropical landscape and Kase and her having fun with lemurs, plus a group photo with actor — and rumored flame — Kevin Costner, who was a guest at the tournament.

“It’s an incredible time, and one I use to relax, rest and play [with] my son!” Jewel wrote of the trip in her post’s caption.

She also gave a shoutout to the 68-year-old Yellowstone star for being “kind enough to mentor” the kids participating in the event.

Jewel and Costner reportedly were affectionate while on the British Virgin Islands.

In photos obtained by TMZ, Costner was snapped with his arms wrapped around Jewel while sitting behind her as she stood and gave a speech to attendees of the event. Both smiled as his hands rested on her waist and she spoke into a microphone.

Two sources there told TMZ there was a "rather new" romance between the two, with the pair making the round trip flight to the Caribbean together and hanging out there for more than a week.
