LUDACRIS AND FRIENDS: For his second annual Ralph Lauren shopping benefit, Ludacris added some female stars to his roster of hip-hop heavy hitters. Fergie, Ciara and India Arie turned out for the event Thursday at the Lauren flagship in Atlanta's Lenox Square, along with Dallas Austin and Chaka Zulu, producer of Ludacris' Disturbing Tha Peace label. Many guests, including Ludadris in a Purple Label pinstripe suit, and Ciara in black-and-white leather from the 40th anniversary collection, were decked out head-to-toe in Ralph Lauren. Fergie, a surprise guest, mixed it up. "My dress is Dolce & Gabbana, my belt is Chanel and my shoes are Versace," she said. "I can never just settle on one designer." The event drew 450 people and 15 percent of the evening's sales went to the Ludacris Foundation, which helps youths and their families.
