Kelly Osbourne: A Not-So-Pleasant Visit in Sydney, Australia? [PHOTOS]

Kelly Osbourne arrived in Australia for the re-launch of Cleo magazine where she is a guest celebrity columnist. However, the 28-year-old British TV star appears to have a not-so-pleasant stay after she reportedly called the hotel staff a "twart" and had a "paranoid outburst" against a Sydney journalist during an interview.

Kelly Osbourne allowed the interview to be conducted in one condition: questions about her family especially the topic about her father, rock music legend Ozzy Osbourne, relapsing to alcohol and drugs dependency.

"Your first column in the magazine is called 'Life Is Just Shit Sometimes'. Have things gotten any better since you wrote it?" the unnamed journalist asked Kelly Osbourne but the ambiance suddenly changed. "You are trying to f***ing turn this around and get shit on my family, aren't you?" Osbourne reportedly said to the journalist.

Meanwhile, other unnamed backstage sources claimed that Kelly Osbourne had a "tantrum" and even displayed a spoiled-brat behavior after she was questioned about her father's current condition.

Another not-so-pleasant encounter that Kelly Osbourne had involves a casino security staff who allegedly treated her "like a criminal." She expressed on Twitter her dismay by calling the staff a "first class twat" after questioning the UK driver's license that she owns.

THE Star yesterday said an incident involving guest Kelly Osbourne had been "resolved" after the British B-lister lashed out at the casino's security this week.

A spokeswoman for The Star stated: "Our security team member asked her for additional ID as she was only carrying an international driver's license, which is standard procedure. The matter has now been resolved with Ms. Osbourne and we are looking forward to further hosting her."

Kelly Osbourne was quick to backpedal on the issue on her Twitter account @MissKellyO. "I never yelled at a reporter I defended my family as I always will! I know why he was absent last night; he wanted to make up a story. #lies," Osbourne wrote. The British rock child further posted a "Thank you" Twitter message to The Star for showing her hospitality during her Australian visit.
