Nicole Ritchie, author

Paris Hilton's sidekick has written a novel about the adopted daughter of a pop star who lives la dolce vita in Hollywood. At a book signing last week:

A teenage boy, wearing lip gloss and a hint of mascara, walked away from the table hyperventilating as he clutched an autographed copy of "Diamonds" close to his chest. "Oh ... my ... God," he said between deep breaths. "Nicole just said I was cool! Nicole just said I was cool!" And so it went for nearly two hours, Ms. Richie scribbling her signature and sprinkling happy dust while unabashedly giddy fans fawned all over her.

...

"Her body is perfect, her hair is perfect, her outfit is perfect, her makeup is perfect," said one teenage boy with flat-ironed hair. "I love everything about her." Judith Regan of Regan Books was equally enchanted. "She's like a little beam of light," Ms. Regan said. "I really regret that she's not available for my son."
