NEW PICS: DIDDY'S 'THE REAL WHITE PARTY' IN THE HAMPTONS 9.02.07

Enforcement was strict last night at P. Diddy's annual White Party - with the rap mogul's security turning away guests for wearing so much as a stitch of non-white attire. Sources inside told Page Six one unfortunate man was made to strip off his cream-colored pants in the street, in exchange for a pure-white pair provided by Diddy. White was de rigueur. Standing on a railed walkway next to his house, Combs sent home a guest wearing a cream-colored dress, and the Piano Man's (Bily Joel) wife, Katie Lee Joel, opted to return home when her dress, also a shade of cream, did not meet the expectations of fashion police out front. Even a Rolls-Royce parked in the driveway was white. The hip-hop mogul's annual White Party, which he has held in St. Tropez in recent years, featured a white carpet to go along with the white dress code. "This party is up there with the top three that I've thrown," Combs said. "It's a party that has legendary status. It's hard to throw a party that lives up to its legend." Combs explained the difference between throwing his famous White Party on the Riviera versus at his first fabulous home. "In St. Tropez, people were so excited, they couldn't stop screaming. They screamed for six hours," he said. "This is the first house I bought when I came into success," he said. "This is the first party I threw. Our party was to give back to people and have all my friends from all walks of life get together."

After 8 p.m., children were told to clear out, but that didn't stop model Kim Porter from showing off D'Lila Star and Jessie James, the 8-month-old twin girls she shares with Combs. Guests said there were also fire eaters and a trapeze artist. Doug E. Fresh was the DJ, but Combs asked for the music to be turned down at one point so the party could be "grown and sexy."
