By Emily Feimster and Stacy Jenel Smith n the last few years, there have been a rising number of famous performers starting families, and if they're not careful it could mean more rich, neglected kids going to extremes to get attention. Growing up in the fast-paced Hollywood scene can prove to be difficult for some. What you end up with is Families Gone Wild!\With news that 19-year-old Kelly Osbourne has checked into a drug rehabilitation center for an addiction to painkillers, the Osbournes are back in the tabloid spotlight once more. It would be difficult to find a more wild show business family, especially considering that it all began with heavy metal papa, Ozzy - who got the wild times started in the 80s when he bit the heads off of bats, was arrested for strangling wife Sharon while drunk, and was treated for alcoholism.

Sharon has been the topic of tabloids after several public feuds involving some nasty words.

At 17, their son Jack, who was already a regular at the clubs, became addicted to oxycontin and attempted suicide, then finally entered rehab. He's still found on the party scene, lately sporting a stunning - really - half-Mohawk hairdo.

After Sharon was diagnosed with colon cancer, Ozzy took to the bottle and prescription drugs again but immediately sobered up when his wife left him for four days. We know who's boss.

Daughter Kelly, who is also big into the rock star nightlife and often involved in celebrity cat fights had a nervous breakdown from the bulk of it all. And now she's in rehab.

But the Osbournes are by no means alone. The show business scene is so loaded with extreme families, it must be attributable to our town's combustible mix of artistic temperament, fame, lots of money, and either a real or perceived license to do just as one wishes. The Jacksons, the Fondas, the Carradines - among them you will find family members who've done things like living in a tree (Peter Fonda), sitting on top of a trailer dressing room strumming a guitar while very zoned out (David Carradine), and exposing a breast during the Super Bowl half time show (like you don't know!)

Among the Hollywood wild bunch, the Arquettes stand out. Some readers will be old enough to remember family patriarch Cliff Arquette, best-known in his comedic guise of cuddly-yet-twisted grandpa-like character Charley Weaver, once a fixture on "Hollywood Squares." Son Lewis and family - including daughters Patricia and Rosanna and sons David and Alexis -- spent five years living on a commune until relocating to Los Angeles.

"It was in the seediest area of Hollywood. I got to know the addicts, runaways, hustlers and prostitutes better than I did my own brother and sisters," said David, who was addicted to drugs when he first met his now-wife Courteney Cox. He kicked the problem in rehab. Sisters Patricia and Rosanna used to hang out with a number of rock stars and by age 20, Patricia had a son by musician Paul Rossi and years later was in a tumultuous six-year marriage to Nicolas Cage. Their flamboyant brother Alexis makes headlines as the drag queen "Eva Destruction." He's outspoken, has posed for gay magazines, and has starred in a number of risqu? films. His "like me or don't" attitude can be a bit of fresh air in this town.

For years the Sheens were tabloid regulars. Leading the pack was Charlie Sheen who has always been open about his years of excess drugs, drink and promiscuous sex. The actor has been arrested for driving under the influence and also charged for battery against an ex-girlfriend. He was hospitalized for a drug overdose until he finally entered rehab in 1998. Not to mention that he regularly hired hookers and dated adult film stars. His brother Emilio Estevez partied with the Brat Pack since he and Charlie hardly spoke for over a decade. And can you believe that their respectable dad Martin has reportedly been arrested over 70 times! Ok, so it was mainly for liberal protests but it's still not something you'd find on the average person's rap sheet.

Drew Barrymore was born into a multigenerational show biz family famous for its love of being in the spotlight - and for excess. Her mother first introduced the young actor to the Hollywood party scene which only escalated from there. At age nine Drew got drunk for the first time and was in rehab by 14. She posed nude at 17, was married for two months, and her drinking and drug use culminated into a suicide attempt. Drew severed ties with her mother for almost a decade and cleaned up her act, though she still occasionally kicks up her heels - and more - at clubs and parties.

One can only imagine what the next generation of show business royalty might bring.
