Ivanka Trump's son stole the show as the Kushner family boarded a water taxi in Venice to attend the lavish $20million wedding of jeff Bezos and Lauren Sanchez.

Theodore Kusher, 9, waved for cameras from the boat channeling British Prince Louis who is known for loving the camera which forced Princess Kate to give him a stern two-word warning on the Buckingham Palace balcony.

Ivanka joined a swathe of A-list celebrity guests for the wedding and was even compared to a huge film star as she shows off her legs in stunning pink gown.

The Venice wedding bonanza of the Amazon founder and Sanchez reached its third and final day Saturday after the couple tied the knot a day earlier in front of around 200 celebrity guests in a secluded area of the lagoon city.

Details of the much-anticipated wedding ceremony Friday night were kept tightly secret, until Sánchez Bezos posted to Instagram a photo of herself beaming in a white gown as she stood alongside a tuxedo-clad Bezos, the world’s fourth-richest man.

Athletes, celebrities, influencers and business leaders converged to revel in extravagance that was as much a testament to the couple’s love as to their extraordinary wealth.

A string of water taxis cut through the lagoon to bring Bezos, Sánchez Bezos and their guests to the tiny San Giorgio island, across the lagoon basin from St. Mark’s Square, where the couple held their private ceremony. Paparazzi in their own boats followed close behind in a controlled chase, trying to capture the couple and their guests on camera, as police on personal watercraft patrolled a no-go zone.

The celebrations are expected to end later Saturday with a large party in a former medieval shipyard, amid high security.

Most guests arrived between Thursday and Friday. The star-studded list included names like Oprah Winfrey and NFL great Tom Brady.

The wedding has divided Venice, with some activists protesting it as an exploitation of the city by the billionaire Bezos while ordinary residents suffer from overtourism, high housing costs and the constant threat of climate-induced flooding.

One group called Extinction Rebellion staged a small protest in St. Mark’s Square on Thursday featuring a masked bride and groom and people holding posters decrying climate change and income inequalities.

“The planet is burning but don’t worry, here’s the list of the 27 dresses of Lauren Sánchez,” read one, a reference to the bride’s reported wedding weekend wardrobe.
