While some celeb assistants taste stardom, most quietly toil away to keep their big-name bosses happy.

Not every star has an assistant. Samaire Armstrong, who plays one on the "Entourage," show, doesn't have one off-screen. "I have a housecleaner, but I can take care of myself."

But "Entourage" producer Mark Wahlberg has an assistant to "wake me up and make sure I get ... (to places) on time. He's more like a personal manager."

Dick has one because he's "super lazy" and doesn't like to drive.

Eddie Roche, who worked for actor Alan Cumming for two years, got that gig after meeting him during the production of the 2000 film "Company Man."

"I dealt with the accountants and agents, fielded e-mails and coordinated with his publicist at PMK," says Roche, 29. "I took care of his dog, Honey, when he was away. She became my dog as well."

Novelist Howard saw a job listing and was hired by Roseanne and Tom Arnold in 1994. She got "sucked in because you just want to be a part of that world, be around celebrities. But then you find out that it's absolutely insane."

Howard was on call 24 hours a day. She screened calls, booked stylists and, as Roseanne's personal shopper, bought everything from Kleenex to a Hummer car.

The payoff? "If you're interested in show business and working in Hollywood, in a lot of these jobs, you have to start out as an assistant," Howard says. "It's all about networking."
