Lauren Sanchez risked a serious wardrobe mishap as she nearly spilled out of her bikini top while she was soaking up the sun with her husband, Amazon tycoon Jeff Bezos, and their famous friends in St. Barts this week.

The newlywed, 56, sported a tiny, zebra-print bikini top as she enjoyed a gorgeous sunset on Bezos' $500 million superyacht in the Caribbean on Tuesday.

Sanchez showed off her ample cleavage in the small swimsuit top, pairing it with a white sarong around her waist and matching zebra bottoms. 

She kept things casual with her hair in a high ponytail, and was also seen carrying around a pair of small, black sunglasses.

At one point, the Fly Who Flew To Space author appeared to be texting someone on her iPhone, as she held the device in her hands.

Earlier in the day, the couple hosted some famous friends on the yacht, including OpenAI founder Sam Altman and Hollywood superstar Leonardo DiCaprio, along with his much younger girlfriend, model Vittoria Ceretti.

Since arriving in St. Barts, it looks like the couple has been having tons of fun as they try to get some relaxation in before 2026 begins.

Earlier this week, they were spotted partying with bikini-clad bottle service women while celebrating a friend's birthday at Nikki Beach.

In a video that has since attracted a lot of attention online, 56-year-old Sanchez, dressed in a denim mini skirt and skin-tight brown top, stood on her seat and danced as she recorded the jubilations on her phone.

Meanwhile, her husband Bezos, 61, clapped animatedly as he sat beside her. He wore a blue shirt and kept his eyes protected from the sun with a pair of shades.

In the clip, initially shared by Page Six, staff were seen striding into the venue with a huge bottle of champagne complete with a sparkler sticking out of the neck.

Women in bikinis also waltzed in holding sparklers with one man riding in on a motorbike.

However, many people on social media didn't seem to approve of the couple's partying, as they labeled the moment 'tacky.'
