Police and city workers were called in to handle the crowd and a lane of traffic was closed as Paris Hilton unveiled her clothing line Thursday at a trendy boutique.

The heiress, author, singer, perfume designer and reality-TV star unveiled the line at Kitson, a boutique known for its celebrity clientele. The lane was closed for pedestrians' safety, a city spokesman said.

Clad in a gold sequin mini-dress, Hilton, 26, emerged from a black SUV to a throng of fans who spilled into the street. Inside the store, Hilton was all smiles.

"It's a dream come true to have my own clothing line," she said. "It's just Paris style: fun, bright and flashy."

The collection, which Hilton described as "really comfortable" and "really affordable," includes shoes, T-shirts and jeans. Hilton said she spent a year submitting and approving designs.

"It's just from my closet to their closets," she said. Additional pieces will be released next month, she said.

The heiress also discussed other newsy matters in her life: her pregnant pal, Nicole Richie ("She's going to be a great mom," Hilton said), and the pending sale of her Hollywood Hills home.

"I'm going to miss my house because I love it. I really designed it to be my perfect taste," she said. "But too many people know where I live and I'd rather be in a gated community."
