His hands are full.

Jeff Bezos spanked his fiancée, Lauren Sánchez, as she sunbathed in a thong bikini on their $500 million superyacht Sunday.

The Amazon founder was captured with his hand in motion to playfully smack the former reporter’s backside while she relaxed on a sun lounger near Cannes, France, as shown in photos acquired by the Daily Mail.

Bezos appeared to rub all over Sánchez’s body in other snaps, also leaning over to passionately kiss her.

At one point, the billionaire businessman caressed his soon-to-be wife’s head near his lap as she tanned.

The mother of three seemed to be enjoying her time on the luxurious yacht, as she was observed lifting her arm to dance while seated with her legs spread on the chair.

Sánchez, 55, showed off her toned beach body in a leopard-printed bathing suit for the outing, completing her look with a straw bucket hat.

Bezos, for his part, rocked a blue short-sleeved shirt, printed swim shorts and aviator sunglasses.

The Blue Origin owner, 61, purchased the lavish mega-yacht, named Koru, in 2021.

The vessel is reportedly 417 feet long, spans several decks and has three huge masts, as well as its own support yacht with a helipad.

The yacht also appears to have a wooden figurehead bearing a striking resemblance to Sánchez.

Koru is one of the largest sailing yachts ever built in the Netherlands, the unofficial capital of boat-building for the uber-rich.

Their day on the boat followed Sánchez’s bachelorette celebration with celebrity friends Kim Kardashian, Kris Jenner, Katy Perry, Eva Longoria, and others in Paris.

The ladies’ activities kicked off last Thursday, with the group enjoying dinner at the historic Lafayette’s Paris restaurant.

The following day, Sánchez and the women headed to lunch before letting loose during a private boat party.

The bride-to-be and Bezos are set to wed in front of more than 200 guests this June in Venice, Italy.

In March, Page Six reported that invites for the couple’s nuptials were sent out to stars including Gayle King, Oprah Winfrey, Ivanka Trump and Leonardo DiCaprio, among other A-listers.
