The Hamptons once again served as a playground for the starry set as celebs descended on the Long Island community last weekend for a variety of events. Toni Braxton kicked things off by wowing fans, including Alec Baldwin, at a July 29 VH1 Save the Music benefit in East Hampton. The next day Kelly Ripa joined hundreds of shoppers at the Super Saturday designer yard sale in Water Mill, which raised $2 million for the Ovarian Cancer Research Fund. Just down the road Matt Dillon and Vivica A. Fox met up with polo ponies and a lion cub (courtesy of South African Tourism) at the Mercedes-Benz Polo Challenge. That evening a parade of Mercedeses headed to Russell and Kimora Lee Simmons's East Hampton home for their annual Art For Life fund-raiser. Among the 1,000 guests: Cynthia Nixon, P. Diddy, Usher, Bon Jovi and Alicia Keys. Sunday morning Kimora Lee surveyed the damage. "My grass is trampled over," she told us. "But what a weekend!"

Forget those reports of Ashlee Simpson's hooking up with Wilmer Valderrama. At E!'s Summer Splash party at the Hollywood Roosevelt Hotel's Tropicana Bar Aug. 1, Jessica's little sis showed up with none other than her sometime boyfriend Ryan Cabrera. "Wilmer's one of my best friends," said Simpson, holding Cabrera from behind. "We always laugh when people say we're together." The on-again, off-again couple, who reportedly broke up in August 2004, held hands and acted cozy throughout the evening. When asked if she and Cabrera had rekindled their romance, Simpson coyly responded (as Cabrera leaned into listen), "Me and Ryan? We're really good."

Paris Hilton and Paris Latsis's summer-long engagement party sailed into treacherous waters July 31. Despite rough seas, the couple set off from Saint-Tropez on a yacht bound for the Italian island of Sardinia. They soon ran into 12-ft. waves in the Mediterranean. "It felt like we were living The Perfect Storm," says Hilton pal Allison Melnick, calling Insider from Italy. She was on board with guests including Nicky Hilton and her beau, Kevln Connolly. Fortunately, the group made port Aug. 1—more nauseous than before but safe and sound.
