Avril Lavigne runs around naked when she is drunk.
The Canadian singer, who is married to Sum 41 rocker Deryck Whibley, admits she enjoys stripping off after a few drinks.
She said: "I've been known to run around naked when I'm drunk.
"One time I was drinking whiskey, and I was so loud, someone called the police.
"I have a side to me that's a bit delinquent and I get myself in trouble. I like to drink and party and speak my mind. But when it comes down to it, I'm a good person and I wouldn't deliberately hurt anyone."
Although she may flash her flesh when intoxicated, the 22-year-old rocker isn't prepared to use her sexuality to sell records.
The 'Girlfriend' singer told Sunday magazine: "Image is a personal choice. I'd rather be seen as me than for not wearing anything. When I first started out in music I was 17. I didn't want to wear the clothes that everyone wanted me to wear. I wore my tank top and Doc Martens boots and I'm glad I did because I was so different from everyone else."
