Paris Hilton and her boyfriend, River Viiperi, celebrated their one-year anniversary dating in Cannes over the weekend. Spies said that the pair was smooching in celebration aboard tech billionaire Michael Saylor’s yacht, called Harle, Saturday night. The boat bash was officially a party for director and former Monty Python member Terry Gilliam’s new movie “The Zero Theorem.” Also at the fete was Christoph Waltz, who stars in the Gilliam film and is a Cannes juror this year. Hilton and Viiperi were also seen in a lip-lock at another Nikki Beach party. Among other hot yacht parties this week, Alec Baldwin and Hilaria Thomas are expected to be on a boat tonight to celebrate the premiere of James Toback’s Cannes film “Seduced and Abandoned,” which was just bought by HBO.
