Lauren Sanchez flaunts her enviable curves in barely-there red dress as she celebrates 54th birthday celebrations during lavish bash

Lauren Sanchez flaunted her enviable curves in a barely-there red dress as she celebrated her 54th birthday with a slew of her star-studded friends over the weekend.

The former journalist, who is turning 54 on Tuesday, shared a series of snaps from the birthday bash - which appears to have taken place on fiancé Jeff Bezos' multi-million dollar superyacht - to her Instagram on Monday.

She looked stunning at the lavish event, donning a busty red gown that boasted a revealing cut-out right below her chest, a sheer section over her midriff, and a long, flowing skirt.

The low-cut number showcased soon-to-be-Mrs. Bezos' stunning figure and ample cleavage.

She left her long, brown locks in loose waves around her face and wore bold makeup for the party. She went barefoot for the evening. 

Lauren spent the evening celebrating alongside a slew of entrepreneurs and stars including Lydia Kives, who is the wife of talent agent and investor Michael Kives; This Is About Humanity co-founder Elsa Collins; celebrity beautician Jamie Sherrill and businesswoman Veronica Smiley Grazer.

Also in attendance was actress October Gonzalez, who is the wife of Lauren's ex Tony Gonzalez, and her sister, photographer Elena Sanchez Blair.

Lauren and football star Tony were together in the early 2000s, and they welcomed a son, named Nikko Gonzalez, in 2002 before going their separate ways.

'Seeing red,' the 53-year-old captioned a carousel of images that featured her and her pals, who were all also dressed in red, posing together on a boat.

'The day before my birthday I'm overwhelmed with love and gratitude to be celebrating 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 I also just have so much fun with them!'

The celebration reportedly took place off the shore of the Caribbean island of St. Barts as Lauren, the Amazon founder, and their friends were seen partying on the island on Friday evening.

According to Page Six, the group visited the restaurant La Petite Plage, where the birthday girl was seen 'dancing on tables.'

The outlet reported that they were also accompanied by movie producer Brian Glazer, media mogul David Geffen, and Fox and USA founder Barry Diller.

'Everyone was letting their hair down. Lauren got up on a table and danced,' an onlooker told the publication. 'It seemed like they were celebrating someone's birthday.'

While it's unclear when exactly they started dating, Lauren and Jeff's romance was first exposed by the National Enquirer in January 2019, while they were both married to other people.

Soon after it was revealed, the mogul divorced his wife of more than 25 years and the mother of his four children, Mackenzie Scott, while Lauren left her husband, Endeavor talent agency co-founder Patrick Whitesell. 

The businessman - who is the third richest man in the world and has a reported net worth of $172 billion - and the journalist then made their first public appearance together in May of that year, and have been happily in love ever since. 

They got engaged in early 2023, and Lauren opened up about the moment Jeff asked her to marry him to Vogue last month.

She recalled how Jeff popped the question on his $200 million mega-yacht after they enjoyed a romantic dinner under the stars together.

She said Jeff concealed the huge diamond ring under her pillow, and that she almost 'blacked out' when she discovered it at the end of the evening just before they went to bed. 

When asked about their upcoming nuptials, Lauren admitted that they were still in the early stages of planning the wedding, so they didn't have a lot figured out just yet. 

'We're still thinking about the wedding and what it's going to be. Is it going to be big? Is it going to be overseas? We don't know yet,' she dished.

And Jeff made it clear that he was leaving it in her hands, telling the outlet when asked if he was going to be heavily involved in the planning, 'Oh, God, no. Do I look that dumb?'

As for whether or not Lauren will be taking her husband-to-be's last name, she admitted: 'Uh, yes, one hundred percent. I am looking forward to being Mrs. Bezos.'

In recent weeks, Lauren has been sporting a dazzling 'Mrs. Bezos' necklace - a custom Alison Lou piece which sits on a four-karat gold chain and costs a whopping $4,400.

A source told DailyMail.com when she was first seen wearing it last month that the necklace was gifted to her by 'a close friend of the couple.'
