Lauren Sanchez shows off her enviable curves in an orange bikini and TINY tweed shorts as she walks hand in hand with Jeff Bezos in St Barts – before celebrating her 54th birthday with a red-themed party on his yacht

Lauren Sanchez showed off her toned body in an orange bikini top and tiny shorts while enjoying a pre-holiday getaway in St. Barts with her billionaire fiancé Jeff Bezos.

The former news anchor and the Amazon founder were seen walking hand in hand on the French-speaking Caribbean island on Sunday, just days before her 54th birthday.

Sanchez started out wearing a Chanel Formula 1 T-shirt, which retails for a whopping $4,450, which she had turned into a crop top to expose her stomach.

She paired the T-shirt from the French luxury label's Cruise 2022/23 collection with pink and brown Tweet shorts, which also appeared to be from Chanel.

However, she didn't keep her designer shirt on for long.

Sanchez was photographed strolling through St. Barts. She wore an orange bandeau top and her low-rise shorts, which revealed a strip of her matching bikini bottoms.

Her long raven hair was styled in loose curls and she wore glamorous sunglasses to protect her eyes from the sun.

The Black Ops Aviation founder wore a long diamond chain layered with a shorter chain that appeared to have a diamond “B” pendant for Bezos attached.

Sanchez confirmed in a recent interview with Vogue that she will “one hundred percent” take her future husband's last name when they tie the knot.

“I’m excited to be Mrs. Bezos,” she said.

The mother of three completed her island look with a $4,500 white Bottega Veneta Maxi Cabat leather bag and silver sandals.

Bezos, 59, was also dressed casually, wearing a cream T-shirt, light blue pants, Birkenstock sandals and round aviator sunglasses.

The couple were joined by friends including Sanchez's younger sister, Elena Sanchez Blair; her former NFL star Tony Gonzalez; his wife, October Gonzalez; and celebrity skin care expert Jamie Sue Sherrill, best known as “Nurse Jamie.”

Sanchez and Tony have a 22-year-old son, Nikko Gonzalez. She also has two teenage children, Evan and Eleanor Whitesell, with her ex-husband Patrick Whitesell.

The group was seen walking around the marina in swimsuits and shorts before boarding a small speedboat.

Sanchez and her friends are staying on Bezos' $500 million superyacht Koru, which was commissioned five years ago and named after the Maori word for “new beginning.”

The ship, then known as “Project 721,” was built by sailboat specialist Oceanco in the historic port of Zwijndrecht, near Rotterdam in the Netherlands.

The Koru is the second largest sailing ship in the world, surpassed only by the Philippe Starcke-designed sailing yacht A, owned by Russian fertilizer billionaire Andrey Melnichenko.

They told Vogue about their engagement, with Sanchez admitting she “swooned a little” when she saw the massive pink diamond ring Bezos surprised her with.

The couple's week-long voyages aboard the yacht and its 250-foot-long support vessel Abeona over the summer included stops at resorts in Italy, France and Spain.

This time, Bezos invited her friends on board to ring in his bride-to-be's birthday on December 19th.

The night before their big day, they held a red-themed party on the deck of the Koru, where Sanchez and her friends posed for photos in their outfits.

Sanchez was the star of the show in a dress with spaghetti straps, a plunging neckline and a center cutout.

On Monday, she shared a series of photos from the impromptu photo shoot on the superyacht on Instagram.

Sanchez stood in the middle of her friends, who also wore various shades of purple. She also took a special family photo with Elena and October.

The final snapshot in the post is blurry and shows her laughing with Elsa Collins, founder of The Ideateur and wife of basketball coach and former NBA player Jarron Collins.

'See red!' she wrote in the caption. “The day before my birthday, I am overwhelmed with love and gratitude to celebrate with these incredible women who are such a big part of my life.” (Some are not here.)

“These women are not just friends, I consider them family, I trust them and love them deeply. “Let's not forget that I also just have so much fun with them!”

Sanchez's plans for her actual birthday remain unclear, but Bezos took to his Instagram Stories on Tuesday to pay tribute to his future wife.

The world's third-richest man shared a photo of the licensed pilot flying a helicopter and wrote: “Happy birthday Lauren, I love you baby.”

Bezos announced last month that he and Sanchez were moving from Seattle to Miami to be closer to his parents.

This year he bought two neighboring properties on Indian Creek for a total of almost $150 million.

The couple will feel right at home on the wealthy island known as the “billionaire's bunker,” where their neighbors will include retired NFL star Tom Brady, former first daughter Ivanka Trump and singer Julio Iglesias.
