The couple announced their engagement last June after Busson presented Thurman with some serious bling: an eight-carat diamond surrounded by 20 smaller stones. Thurman, 39, and Busson, 46, have been spotted at a luxury resort on Eleuthera. According to marriage requirements for the Bahamas, the couple must be in the country for at least 48 hours to obtain a marriage license. Licenses are issued by the Registrar General, the same official who issued a marriage license to Mariah Carey and Nick Cannon last year. The Registrar General's office declined to comment on whether they have issued a marriage license. If the couple do exchange vows, it will be the third marriage for Thurman, who has a son and daughter with her ex (since 2004), Ethan Hawke. Her marriage to Gary Oldman ended in 1992. Busson has two sons with former supermodel Elle Macpherson, from whom he split in 2005.

Uma Thurman is was a big tease. The Kill Bill babe was rumored to have married Arpad Busson in the Bahamas over the weekend, and, with the actress' camp mum, eagle-eyed reporters and photographers attempted to scope out her left hand and draw a conclusion. She stumped them by wearing bright baubles that were neither a wedding band nor the 8-carat engagement stunner she was reportedly given when Busson proposed last June. They can relax now. "Uma did not get married," Thurman's rep, Stephen Huvane, tells E! News. Instead of the big diamond, the star wore a topaz piece to an event for Cookie magazine Monday, and a shiny gold accoutrement to a press conference for the Tribeca Film Festival earlier today. At the fest's kickoff, the question-and-answer period was kept brief and, sadly, on topic. The actress did announce the jurors for the various competitive categories, many sparkling celebs among them, including herself, James Franco, Bradley Cooper, Meg Ryan, Mary-Kate Olsen and Debra Messing. People kicked off the buzz about a Thurman-Busson union on the island of Eleuthura on Saturday, claiming the couple had obtained a marriage license and were prepared to swap vows. When they eventually do wed, this will be the third marriage for Thurman, following her divorces from Gary Oldman and Ethan Hawke.

The charms of Italy's most romantic city isn't lost on Salma Hayek's wedding guests, who started arriving in Venice, Italy Thursday for the star's second wedding celebration with husband François-Henri Pinault. Despite cloudy skies, actor Woody Harrelson and wife Laura Louie enjoyed a twilight hand-in-hand stroll around Piazza San Marco, while other guests – including Hayek's ex-boyfriend Ed Norton and actor Olivier Martinez – were seen enjoying the sites of the city. The wedding weekend kicked off Friday with a rehearsal dinner at the Punta Della Dogana, one of Venice’s most historic buildings, which guards the south entry of Venice’s Grand Canal. The Carnival in Venice-style masked ball was held inside a white tent in the courtyard with many guests, including Charlize Theron and boyfriend Stuart Townsend, wearing black Venetian masks. Also in attendance were former French president Jacques Chirac and wife Bernadette. Others expected at the celebration are Penélope Cruz, Ashley Judd, Luis Miguel and Lucy Liu. The site of the rehearsal dinner has been used by Venetian merchants since the 15th century. After the buildings fell into disrepair, the city awarded the lease to Pinault's father, who has since spent $70 million on renovations. The structure will open to the public as the Pinault Foundation Centre for Contemporary Art on June 6. Earlier this month, Hayek, 42, told PEOPLE, "I think a wedding is about love, friends, family and fun." The actress-producer and Pinault, 46, the CEO of luxury-goods company PPR, are parents to daughter Valentina Paloma, born in September 2007.

ET's special correspondent Cheryl Woodcock was among the guests at the Saturday nuptials between Heidi Montag and Spencer Pratt -- and she reveals the details from inside the ceremony! Cheryl, who attended the nuptials with her daughter Skyler, says the ceremony was nothing short of "tasteful and elegant." "The ceremony was based on trust, hope and love," she says. "You could really see that this young beautiful couple was truly in love, and their intentions today were to say their vows in front of God and their closest family and friends." Heidi's father walked her down the aisle wearing a cowboy hat, which Cheryl learned was a request made by Heidi. "He looked shockingly handsome and she looked stunningly beautiful," Cheryl enthuses about the couple, adding that Heidi's long, sparkling veil "took everyone's breath away." Cheryl says the ceremony location was beautifully adorned with cream and white roses, while the bridesmaids wore one-shouldered, buttercup-yellow gowns. "The Hills" stars Brody Jenner and Audrina Patridge were also in attendance, Audrina wearing a strapless, navy blue mini-dress. One of Heidi's bridesmaids was Spencer's sister, Stephanie Pratt, who is also a cast member on "The Hills." Cheryl noted that as Stephanie made her way down the aisle, she mouthed the words "I love you" to her brother, who whispered them back to her. Before Heidi made her way down the aisle, Spencer looked excited, smiling and dancing around as he awaited his big moment. After the vows, it came time for Heidi to throw the bouquet -- and Cheryl says it was none other than "Laguna Beach" alum Kristin Cavallari who caught it! Heidi and Spencer's wedding ceremony was followed by a reception at the Beverly Wilshire Hotel. The nuptials were captured by "The Hills" cameras, and will air on the hit MTV reality series.

"I saw him and I had a crush on him. He's not going to tell you that, but I saw him and I was like, 'I have a crush on him. I'm going to talk to him.' And then I did," she told PEOPLE.

NBA basketball player Brian Cook, known for keeping his cool on the court, had some last-minute jitters over the weekend – and nobody could blame him. The power forward for the Houston Rockets stood before about 150 guests and exchanged vows with Victoria Velasquez on Saturday at the Trump National Golf Club in Palos Verdes, Calif. Players from across the league were on hand and one of his two best men was Luke Walton from the Los Angeles Lakers, one Cook's former teams. "I wasn't nervous at all until right before the ceremony," says Cook, "and then I saw her and just knew that it was all good." The five-tiered wedding cake was made of red velvet and vanilla cake with butter cream frosting. But it was the groom's cake – in the shape of a basketball – that caused a commotion. As soon as they cut the cake, several of the players "started throwing cake on Brian!" says a witness. The couple danced their first dance to Stevie Wonder's "Ribbon in the Sky." The bride wore a dress by Priscilla of Boston Platinum Collection and $75,000 worth of jewelry from Adorn Brides. The wedding, which had a purple and turquoise color scheme, was designed by Kathy Mazza of Bella Weddings & Events.
