Kelly Osbourne reportedly got so drunk during a recent flight from LAX to Atlanta that her assistant and a security guard had to carry her out of the plane.

Perez Hilton reported that the British-born Fashion Police star supposedly started out so well. “She was gorgeous when she got on the flight,” an eyewitness said of Kelly Osbourne. “Her makeup was impeccable,” said the source, “Her hair was up in a smart-looking bun, and she was wearing cool shades” to boot.

However, the daughter of Ozzy Osbourne and Sharon Osbourne allegedly proceeded to ruin that chic image by drinking herself into a dazed stupor.

The Perez Hilton source claimed to have seen “a flight attendant bring alcoholic beverages over to the First Class section that Kelly Osbourne occupied.” The attendant repeated the process “at least four or five times,” said the eyewitness.

“And when we landed just after midnight,” the source continued, “Her assistant… had to help her off the plane.”

According to the Perez Hilton source, Kelly Osbourne and her assistant “were the last to leave.” They met up with “a burly security guard” at the airport arrivals lounge. The guard and Kelly’s assistant “basically carried her down the corridor to the airport tram.”

Ozzy’s daughter was reportedly “swaying from side to side” as her assistant and the guard carried her. “Kelly’s hair was hanging down,” said the source, “She was mumbling and her makeup was a mess.”

Kelly Osbourne was not the only member of the Osbourne clan who was feeling down. Her brother Jack Osbourne was recently diagnosed with multiple sclerosis, and her famous dad Ozzy Osbourne had to cancel a concert in Germany because his throat was not up to singing.

Ozzy Osbourne was forced to drop out of a Black Sabbath concert in Germany because of “vocal concerns.”

According to TMZ, German fans feared the worst when the 63-year-old Osbourne suddenly pulled the plug on a Black Sabbath performance at the SAP Arena in Mannheim, Germany this Wednesday.

Sources reported that Ozzy Osbourne was next on the stage after the band Black Label Society finished their set. However, fans were confused when an unknown man walked on stage. Then the fans became concerned after the man announced that Osbourne would be unable to perform due to a medical condition.

A rep for Osbourne informed TMZ that the heavy metal legend was generally okay. But the Black Sabbath front man was having troubles with his voice, so he decided to play it safe and cancel the show.

TMZ reported that Ozzy Osbourne had yet to determine if he would reschedule his concert or simply issue a refund. German concertgoers received instructions to check the venue’s official website.

It’s been a bad week for the Prince of Darkness of Black Sabbath and his star-studded family. Jack Osbourne was recently diagnosed with multiple sclerosis mere weeks after he and his fiancee Lisa Stelly presented their bouncing baby girl, Pearl Clementine. Now it’s apparently the turn of his father Ozzy Osbourne.

Sharon Osbourne fought back tears when talking about how her son Jack Osbourne recently revealed that he had been diagnosed with multiple sclerosis.

Gossip Cop reported that the ‘America’s Got Talent’ judge appeared on ‘The Talk’ for an interview. “He’s doing really really good,” the tearful Sharon related of Jack Osbourne. “And I want to thank everyone for their good wishes and love they’re sending to us.”

Adding that “It’s been amazing,” Sharon believes said that “I really believe that vibes of prayer help” her son Jack deal with his multiple sclerosis.

Mother’s guilt prompted her to admit that “I’m just feeling sorry for myself and that is no good.” Sharon Osbourne also said that she has and her family “have to think positively” in order to weather the crisis.

According to Gossip Cop, Sharon said that Jack would appear on ‘The Talk’ on Wednesday to discuss his diagnosis.

Jack Osbourne and his fiancee Lisa Stelly welcomed their daughter Pearl back in April. Two weeks later, the youngest child of Sharon Osbourne and Ozzy Osbourne was informed that he had multiple sclerosis, an autoimmune disease that attacks the brain and nervous system.

Rockstar couple Sharon and Ozzy Osbourne are currently facing a lawsuit due to illegally extending the backyard of their house in Los Angeles — without permission.

According to the lawsuit filed against the celebrity couple, they annexed a land next to their massive Hidden Hills, Los Angeles home, which is governed by The Mountain View Estate Owner’s Association. The said association claims that Sharon and Ozzy Osbourne built a fence in their backyard which extended roughly 8,500 square feet in the Association’s land. However, the lawsuit did not specify whether Sharon and Ozzy Osbourne were notified of the alleged infringement.

The lawsuit also stated that a land surveyor working for the Association discovered the enroachment on the 2nd of May. Now, The Mountain View Estate Owner’s Association is demanding an order from the court, requiring the Osbournes to remove their fence and stay off its property.

The lawsuit comes after news broke out the Sharon and Ozzy Osbourne have paid off their tax bill for the year 2008, but are claimed to still owe approximately $1.4 million to the IRS. The couple initially gave the feds $700k. The IRS slapped Sharon and Ozzy Osbourne with a tax debt last spring, amounting to $1.7 million.

Last April, Sharon Osbourne explained the reasons on her daytime US chat show, “The Talk” why she and Ozzy Osbourne are behind on their tax bill. Sharon said that she lost track of her family’s finance because she was spending too much time on herself. She also added that although she initially put the blame on her accountant, she was now taking full responsibility for the $1.7 million tax debt.

“Even though he is paid to do a job, the buck stops with me,” Sharon Osbourne said.
