London, Apr 9 : Muggers and robbers need to think twice before they go near actress Vanessa Hudgens, for the `High School Musical' star now keeps herself armed with a taser gun.

The 20-year-old star has recently bought a new Hollywood home, and has confessed that she feels vulnerable living on her own.

To avert any potential danger, the Disney starlet has splashed out on a gun that will zap bad guys with a painful blast of electricity.

"I keep a taser in my purse for self-defence," the Daily Express quoted Hudgens as telling Us Weekly magazine.

She added: "I''m moving into a house by myself and it''s scary." (ANI)
