Heavy metal is one thing. Heavy artillery is quite another.

Kelly Osbourne, the 18-year-old daughter of Ozzy and Sharon, has pulled out of a promotional trip to England because of the risk of terrorist attacks, and after she saw pictures of army tanks patrolling near London’s Heathrow Airport, her British publicist told news outlets.

Kelly was due to perform at Thursday night’s NME magazine awards in the British capital and present a prize at next week’s Brit Awards.

As it now turns out, Kelly — who is currently No. 18 on this week’s singles chart in Britain with her second single, “Shut Up” — didn’t even make the trip from her home in Los Angeles.

“Kelly’s parents were in New York on Sept. 11 when the Twin Towers came down, so you can imagine how they feel,” said spokeswoman Naz Ahmed. “The decision wasn’t taken lightly, and Kelly has thought long and hard about it.”

British police have been warned that al-Qaeda might try to attack London during this week’s Muslim festival of Eid al-Adha. In London on Thursday, police also arrested a man carrying a live hand grenade at Gatwick Airport and evacuated one terminal.

Osbourne’s rep said Kelly “is upset that she can’t come to Britain, because she was really looking forward to it. But as well as herself and her parents, she also has a whole crew and band to think of, and she has decided not to take the risk.”

According to, Kelly wasn’t the only North American expected to pull out of the current music festivities. Cancellations were reportedly also expected from Pink, Avril Lavigne and Justin Timberlake.
