Although Avril Lavigne sings about trying to steal another girl’s guy in her song, Girlfriend, she has harsh words for anyone who tries to steal her husband, Sum 41 frontman Deryck Whibley.
The rock chick says she’ll take on any groupies who try and take Deryck away from her.
"If some girl was going after my man I'd punch them. I don't think stealing any girl's guy is a nice thing - it's totally mean," she says.
The pair married last July.
