50 Cent that his beloved bulletproof lifestyle is subject to a stack of paperwork and permits.

50 Cent, whose real name is Curtis Jackson, was shot nine times in a gun battle in the US three years ago.

Since then he has worn a bulletproof jacket.

He wants to take similar precautions for his December 5 show at Rod Laver Arena, to avoid the fate in the US of slain rappers Tupac Shakur and Biggie Smalls.

"It's not that I'm anticipating that. But in the event that it does happen, I would like to be prepared for it," 50 Cent told the Herald Sun.

Yesterday, 50 Cent's Australian tour promoter confirmed the Customs ban on the bulletproof jacket.

"I know our tour manager is aware of it, so 50's tour manager should be aware of it," a spokeswoman said.

"I am sure they will sort something out."

A Customs spokeswoman said 50 Cent's bulletproof vest is "a prohibited import".

50 Cent will need to apply to Justice and Customs Minister Chris Ellison for a jacket permit.

He must also apply for permits with state police.

50 Cent must also give a detailed reason for wearing the jacket.

His paranoia about getting shot is well founded.

Last month, gunmen fired warning shots while Jackson was at a New Jersey hotel.

Asked if he will wear his bulletproof jacket in Australia, 50 Cent told the Herald Sun: "Probably. It depends on how things are when I get there.

"A different environment means the violence is different. If there is no gun or knife involved, you'll probably get your head punched.

"Wherever you go, people handle their business differently."

Bulletproof jackets are sold in Australia but need strict permits.

They must also be licensed with police and the Private Agents Registry.

Bulletproof jackets cost $500 to $1200.

50 Cent's latest album Get Rich Or Die Trying has sold nine million copies.

His Rod Laver Arena concert is almost sold out.
