Lauren Sanchez, Jeff Bezos Kiss on Water Taxi After Tying the Knot

Jeff Bezos and Lauren Sanchez are in a state of bliss post-wedding, floating like a water taxi through Venice … and locking lips on a ship as hundreds of photogs snapped pics.

JB and LS were spotted in the city Saturday … and, they gave paparazzi a show — full of smiling, waving and, eventually, a big old kiss.

The two are dressed to the nines in the pics … clearly headed to the next big event of their wedding week.

Lauren also gave a wave while standing on some sort of raised platform — unclear if it’s a balcony, but she looked like royalty in the shot.

Worth noting … some protesters in Venice were up in arms about Bezos and Sanchez — both earlier in the week and on Saturday — so, we don’t imagine all the onlookers were cheering for them.

As we told you … Lauren and Jeff had their official wedding ceremony yesterday on San Grigorio Maggiore — an island in Venice — attended by big stars like Sydney Sweeney, Orlando Bloom, Kim Kardashian, Tom Brady and more.

Sources with direct knowledge tell us … Brady was dancing with everyone at the wedding reception after — including Sweeney, and Tom’s ex Brooks Nader — and Bloom made the rounds, too.

Ellie GouldingDJ Kygo and Andrea Bocelli‘s son, Matteoall performed at the reception … and, while the main event broke up around 2 AM, The Gritti Palace — party central for the week of events — was popping until well after 3 in the morning, we’re told.

Tons of celebs — including Kylie Jenner and Oprah Winfrey — are still in town for more wedding events … including one they’re heading to right about now.
