Leonardo DiCaprio, Vittoria Ceretti to attend Jeff Bezos' wedding

Leonardo DiCaprio and his girlfriend Vittoria Ceretti are expected to attend the wedding of Jeff Bezos and Lauren Sánchez in Venice, Italy, this summer. 

A source tells People magazine that the actor, 50, and the 27-year-old Italian model will be among the guests at the highly anticipated event.

The wedding guest list is shaping up to be a star-studded affair, with other notable attendees including Tony Gonzalez, Sánchez's ex-boyfriend, and their son, Nikko, 24. 

Kim Kardashian, Kris Jenner, Katy Perry, and Eva Longoria have already been spotted celebrating with Sánchez, and are likely to be in attendance.

Bezos and Sánchez's wedding invitations have been making the rounds, and they're certainly one-of-a-kind. The cards feature beautiful drawings of flying birds, floating feathers, and rowing gondoliers. 

The invitation reads, "We are excited for you to join us! We have one early request: please, no gifts. Instead, we're making contributions in your honor and with gratitude to you for making the journey to celebrate with us in Venice."

The couple has chosen to make donations to several organizations in lieu of gifts. The UNESCO Venice Office, CORILA, and Venice International University will all receive contributions in honor of the guests. 

"Donations on your behalf are being made to the UNESCO Venice Office to safeguard the city's irreplaceable cultural heritage, to CORILA to restore the vital lagoon habitats that protect Venice's future, and to Venice International University to support research and education for sustainable solutions," the invitation continues.

Venice Mayor Luigi Brugnaro has confirmed that the ceremony will take place in the historic Italian city, but has not revealed a specific venue. 

Only 200 guests will be invited, and the event is expected to be respectful of the city's fragility and uniqueness.
