Prince William and Princess Kate timed their trip to coincide with the famous Mustique Blues Festival, where they hit the dance floor hard.

“Of course they let loose, even Kate!” laughed a longtime waiter at Basil’s. “They were drinking and dancing all night. It’s a party — the music festival is always a good time.”

The couple slipped under the radar thanks to the island’s no-paparazzi policy, but their boozy antics didn’t go unnoticed by the tight-lipped locals.

“I don’t want other guests to overhear us talking about them,” the waiter hushed to The ENQUIRER’s mole. “But I will tell you they were generous tippers,” the staffer smiled. “Of course, they take care of us like we take care of them.”

While William was swilling cocktails, Kate charmed the islanders with her laid-back attitude and healthy glow.

“She blended in so seamlessly. She was able to shop at the little grocery store without anyone bothering her. They have access to a full team of butlers and chefs, but Kate always shops for herself.”

And while William and Kate enjoyed each other and danced under the stars, Kate’s mom, Carole Middleton, babysat the royal children back at the villa, celebrating her 70th birthday.

“Carole was there with the kids so Kate and William could sneak away and enjoy the party,” the insider said.
