Lauren Sanchez looked incredible as she headed out for a boat trip along the river Seine in Paris for day two of her bachelorette party on Thursday.
The bride-to-be, 55, who is engaged to Amazon founder Jeff Bezos, showcased her jaw-dropping figure in a white midi dress as she left her hotel.
The former TV host looked sensational in the skintight garment which she wore with a matching pair of heels.
Letting her brunette locks fall loose down her shoulders, Lauren complimented her outfit with a silver necklace.
She was joined by several friends on the outing including Kim Kardashian who turned heads in a black strapless dress that highlighted her famous curves.
The reality star, 44, also wore a pair of black tights with matching heels and styled her tresses into a sleek updo.
Katy, 40, opted for a daring look for the trip as she slipped into a black leotard which she wore with a black sheer skirt and matching belt.
Also in attendance for the day was Kim's mother Kris Jenner who cut a stylish figure in a black long-sleved mini dress.
The momager, 69, also wore a pair of black tights and boosted her frame with matching heels.
Kris linked arms with Eva Longoria as the group left their hotel with the Desperate Housewives star, 50, looking sensational in a blue turtle neck dress.
Lauren looked in good spirits as the group climbed on deck and went for their trip down the Seine. She was all smiles while enjoying a glass of bubbly with her pals.
The outing came just a few hours after Lauren and her friends enjoyed lunch at L Avenue restaurant in the French capital.
DailyMail.com can exclusively reveal that glamorous journalist Lauren has a full weekend of celebrations planned and kicked off her pre-wedding festivities with a luxury dinner.
A source close to Kim told DailyMail.com: 'Spending girl time at Lauren's bachelorette was a great way to end the week after testifying. She's glad it's over but thankful she was asked to testify as part of the trial.'
Lauren and her famous friends enjoyed dinner at the historic Lafayette's Paris restaurant in Paris, which offers refined French dishes with a modern twist.
Katy, Lauren and four other women previously completed their all-female mission to space aboard Jeff Bezos' Blue Origin rocket on April 14.
The A-list crew travelled for 11 minutes, reaching an altitude of 62 miles (100km) and crossing the Karman Line, the official boundary of space.
Also on board were CBS Mornings co-host Gayle King, film producer Kerianne Flynn, activist Amanda Nguyen, and former NASA rocket scientist Aisha Bowe.
The New Shepard Rocket carried the capsule to the edge of space at nearly twice the speed of sound before detaching and allowing the crew to experience a few minutes of weightlessness.
During that period the crew capsule crossed the Karman Line, technically passing from Earth's atmosphere into space.
The capsule then made the return journey back to Earth, as the unfurling parachutes drew screams from the crew onboard.
Blue Origin Flight NS-31 was the first launch with an all-female crew since Russian astronaut Valentina Tereshkova's solo space flight in 1963.
Katy said ahead of the launch they were 'putting the "a*s" in astronaut'.
Speaking about the latest festivities in Paris reuniting the Blue Origin 'astronauts', a source at Lafayette said Lauren hosted an 'excellent party'.
They shared: 'We recognised a lot of big names, including Kim Kardashian and Katy Perry,' he said. 'They were all delightful, and a pleasure to have here.'
They were treated to starters that included fried chicken, Caesar salad priced at $28 apiece, and $22 Norwegian smoked salmon, and a main course that featured mushroom rigatoni at $31 a head and roasted chicken costing $105 each.
English Channel sole was available at €78, as well as rib-eye steak (€46), caviar on warm potatoes (€75), and truffle on macaroni and cheese (€38). Deserts included crème caramel at €12 each and Rum Barba at €20.
Mory Sacko, 32, is the star chief chef at Lafayette's, and he concentrates on French dishes with an American and African twist.
Asked what the ladies had to drink, the source said: 'Mainly water and soft drinks, although there was a bit of champagne drunk too.'
Among the other friends who joined her was October Gonzalez, the wife of her football player ex Tony Gonzalez, with whom Lauren shares son Nikko, 24.
Lauren is on friendly terms with October, as the pair are often seen socializing with one another on a regular basis.
Not only has Lauren been on vacation with her former partner Tony and October, she regularly attends events with the 44-year-old and they even spent Thanksgiving together last year.
Tony and Lauren separated shortly after Nikko's birth in February 2001.
Lauren and Jeff, 61, are expected to walk down the aisle next month, and the unusual venue for the ceremony is raising some eyebrows.
The couple, who have reportedly booked Elton John and Lady Gaga to perform, could say their 'I dos' on a Venetian island in an open-air theater.
The billionaire, his bride and some 200 guests have reportedly already booked rooms at the best hotels.
Jeff's mega yacht is also expected to be a part of the festivities, although neither the future bride or groom would confirm.
Guests are expected to include: several members of the Kardashian/Jenner family, Perry and her fiancé Orlando Bloom, Leonardo DiCaprio, as well as Ivanka Trump, Jared Kushner, and along with model Karlee Kloss and her husband Joshua Kushner.
President Donald Trump has also reportedly been invited to the nuptials.
Officials from the city of Venice have said they lobbied Jeff and Lauren to hold the wedding there.
Morris Ceron, the director general of the Venice council told the London Times he personally approached the Amazon founder about choosing the ancient city for the wedding.
Lauren and Jeff went public with their relationship in 2019. The pair got engaged in May 2023, after Jeff popped the question on board his $500million superyacht.
Their engagement followed the couple having an affair, which Jeff has admitted to, leading to his divorce from wife of 25 years Mackenzie Scott in 2019 and Lauren's split from husband Patrick Whitesell, who she married in 2005, with whom she shares a son and daughter.
Four years after their affair was revealed to the world by the National Enquirer, Jeff asked Lauren to marry him, providing a pear diamond estimated to be worth at least $2million.
Since then, the couple have flaunted their love around the world, with holidays aboard Jeff's megayacht.
As well as their luxury yacht trips, the couple take trips to five-star resorts, private jet flights and beachside getaways.
They dine in sought-after restaurants, attend elite parties, and mingle with some of Jeff's celebrity friends.
