The celebrity, who has remained infamous for her plastic surgeries, said that she is learning martial arts in order to protect herself in public.
"I can''t afford security, so I practice self-defense and chain punching," the New York Daily News quoted Montag as telling RadarOnline.com.
Montag and husband Spencer Pratt have spent enormously on security in the past but after reportedly blowing 10 million dollars on fancy cars, private jets, and Montag''s music career, the 'Hills' star explained she has had to start watching her wallet.
"I have had to change my life. I can''t afford to go out to the clubs anymore because the sort of protection I need can cost anywhere from 5 to 10 thousand dollards a night...That is actually where all my money went because safety is number one," she noted.
Montag, 24, added that practicing martial arts has given her strength - both inside and out.
"It gives me confidence I didn''t have before. I am doing this self-defense because it gives me inner strength, and I feel safe in my home," she said.
Even after six months of intensive training to eventually become a black belt with the help of trainer Michael Casey, she said she''s "not ready to go out alone yet."
"I'm only 5 feet 2 inches tall and have a small frame so I understand I can''t completely do it alone yet. Which is why I don''t go out as much. It is scary to be out there without protection, people do follow me and you can never be too careful," Montag concluded.
