Note To Potential Muggers of The World: If you come near Vanessa Hudgens, be prepared for a blast from her taser gun.

Vanessa feels a little vulnerable living on her own for the first time, so in bid to protect her new mansion in the Hollywood Hills, the 20-year-old actress has invested in a gun that will zap the baddies with a painful blast of electricity.

“I keep a taser in my purse for self-defense. I’m moving into a house by myself and it’s scary,” Vanessa whispered to Us Weekly reporters this week.
