VIEW FROM THE TOP: For those tourists who could stand the hot, crowded, seemingly endless line to the Empire State Building's Observation Deck on Thursday, there was a treat beyond the legendary view. At the top was singer Rihanna, bedecked in a Cartier tiara and a short printed PPQ dress. There to help Cartier North America president and chief executive officer Frédéric de Narp switch on the building's lights to red in honor of Love Day, Rihanna (who is said to be dating Chris Brown) said that while she is "not in love" at the moment, she is in love with the tiara she was loaned by the company for the event. "My tiara is a little street," she said of the pricey gemstone studded headpiece, which was worn to the side. "Well, the tiara isn't really street...I moved it to the side, it's a little rock 'n' roll." De Narp and his team flew in from Los Angeles late Wednesday night, where the company threw its third annual Love event, which was attended by the likes of Janet Jackson and Fergie.

WEDDING BELLE: A little bit of Hollywood is coming to the Hamptons next weekend, when actress Joy Bryant weds her beau of over a year, movie stuntman David Pope, in a beachside ceremony at a private house in Amagansett. The 31-year-old Bryant will wear a dress made for her by designer Angela Missoni and change into a floral print Missoni number to celebrate with her 100-plus guests, while her 37-year-old groom will don a pale gray Calvin Klein Collection suit. The last well-known bride to wear Missoni was Charlotte Rampling at her South of France wedding to her then-agent, Bryan Southcombe, over 35 years ago.

This wedding might come as a surprise to many. Bryant managed to keep her engagement out of the tabloids, unlike most starlets.

And there won't be a long honeymoon: Bryant is heading straight to work on her new TV show, "Virtuality."

HOT STUFF: Actor Emile Hirsch, who recently made ripples with Sean Penn's "Into the Wild," has posed for larger-than-life images wearing Valentino's new spring 2009 looks. The black-and-white photos were just shot in Milan by photographer Gian Paolo Ferrari, and will serve as the backdrop for the collection designed by Ferruccio Pozzoni at the June 27 presentation in Paris. Hirsch will be on hand at both the Milan and Paris presentations.
