Why Squeaky Clean Stars Like Kim Kardashian Are in, and Troubled Bad Girls Like Paris and Lindsay Are Out!

Notice to celebrities -- the time for drugging, and partying it up beyond the max, is OVER!

Take a look around you, check out who's landing TV shows, movie roles, product endorsements and oodles of fans -- it's the new Hollywood goody goodies, not the toxic trainwrecks.

Kim Kardashian who told Jay Leno "I've never been a drinker, I've never gotten into drugs," when she dropped into his Aug. 31 show, is the new Queen of the squeaky clean set. And listen, you need two hands to list all her business ventures. Besides starring in the reality show, Keeping Up with the Kardashians, and executive producing The Spin Crowd, starring PR meisters Jonathan Cheban and Simon Huck, she's got a clothing line for Bebe, Kardashian Glamour Tan for Sephora, Fusion Beauty, Kim Kardashian perfume etc. -- etc. -- you get my drift!

Other members of Hollywood's new squeaky clean club are Justin Bieber, Taylor Lautner, Taylor Swift, Selena Gomez, The Jonas Brothers, Demi Lovato, Amanda Seyfried, Jessica Alba, Heidi Klum and former heroin-addict/new healthy mom, Nicole Richie.

Can we talk about how Bieber and Taylor Swift have burneded up the charts, filled concert stadiums and have broken into movies. Hey, they're too busy recording, performing and having fun, to drug-it-up!

It's no longer in any way cool to get-arrested Paris Hilton-style for dropping a bag of cocaine out of your "it's-not-my-purse," or show up at your probation officer meeting in a sheer top, Lindsay Lohan-style.

Don't believe me? Here's what one Hollywood manager tells his clients: "Directors and producers are squeamish to work with actors who have reputations as party animals," he says:

Lately, directors and producers have been really thorough before they cast anyone... There was a time when directors didn't get involved with personal stuff. They'd turn a blind eye. Nowadays they want to know what's going on with their stars. If the stars turn out to be a druggie or an alcoholic, it's on their shoulders.
