That’s one way to pop some bubbly.

Jeff Bezos and Lauren Sánchez recently threw a foam party on Jeff’s superyacht to celebrate her son Evan’s 19th birthday. This fun celebration took place over the weekend, right before their upcoming star-studded wedding.

The tech mogul and his soon-to-be wife were seen flirtatiously dancing in the soapy bubbles aboard the massive floater off the coast of Europe Sunday.

A shirtless Bezos flaunted his muscles as he got handsy with Sánchez, who wore a cheeky pink-and-black string bikini.

The former journalist, 55, and her fiancé, 61, coordinated in hats and sunglasses to protect them from the glaring sun and prying paparazzi.

At one point, the couple wrapped their arms around each other as they swayed and smiled while surrounded by other friends.

Sánchez was also seen sweetly snapping a photo of Bezos on her phone as he played in the suds.

Other pics from the outing showed the Amazon founder and Sánchez cuddled on a lounge chair as Evan and his friends enjoyed the luxurious activities aboard Bezos’ $500 million super yacht dubbed Koru.

The group of pals even gathered on the spanning deck to hit golf balls into the sparkling sea.

Sánchez shares Evan and 17-year-old daughter Ella with ex-husband Patrick Whitesell. The two were married from 2005 to 2019.

The brunette bombshell also co-parents 24-year-old son Nikko with ex Tony Gonzalez.

The mom of three celebrated her middle child’s birthday just days before she and Bezos are expected to say “I do” in a lavish Venetian wedding this week.

Bezos and Sánchez have been spotted showing PDA all over Italy ahead of their impending nuptials.

Page Six exclusively reported that the lovebirds quietly donated to a number of local charities in Venice as part of their wedding planning process.

We’re told they made donations in honor of some of their expected A-list wedding guests like Oprah Winfrey, Leonardo DiCaprio, Kim Kardashian, Bill Gates, Barbara Streisand and Ivanka Trump.

While Bezos and Sánchez have managed to keep their wedding location under wraps, rumors swirled that they could walk down the aisle on his superyacht, the island of San Giorgio and a large exhibition space called Scuola Grande della Misericordia.

They are reportedly sourcing almost all of their wedding goods from Venetian vendors, per the Associated Press, turning to the city’s oldest pastry maker, Rosa Salva, and Murano glass blower Laguna B.

Page Six broke the news in May 2023 that Bezos and Sánchez got engaged after dating for five years.

He presented her with a massive 20-carat diamond engagement ring valued to be worth an estimated $2.5 million.

Bezos was previously married to MacKenzie Scott from 1993 to 2019. They share four kids who they’ve kept out of the spotlight.
