Jeff Bezos and Lauren Sanchez have invited celebrity friends like fellow space traveler Katy Perry, Oprah Winfrey, Mick Jagger and Ivanka Trump for their Venice nuptials later this month, but the couple hopes to put a spotlight on Venice’s traditions during the celebrations.

Protesters in Venice are trying to stop Amazon founder Jeff Bezos from marrying Lauren Sanchez in their crowded city. Celebs are expected to swarm the area for three-day event.

A group protesting Bezos’ upcoming Italian wedding, “No Space for Bezos,” held a protest in a Venetian town square on Friday.
