Remember when Avril Lavigne tried to make it in Hollywood? She dyed her hair blonde, took to wearing - gasp! - a dress and started turning up at film premieres wearing more make-up than Dame Edna. It didn't work: she looked about as comfortable as Elton John in a monastery and the highlight of her acting career remains a voice role in Over The Hedge.

Fortunately, just in the nick of time, she's returned to music with an utterly infectious pop-punk single. 'Girlfriend' sounds like Joan Jett singing 'Mickey': all snarling attitude, driving guitar riffs and chantalong choruses. There's a sneaking suspicion that, at 22, Lavigne is a bit too old to be acting quite this teenage. And, really, there's no excuse for the rap where she tries to rhyme "finger" with, ahem, "better". But who cares? 'Girlfriend' is as big, dumb and likeable as a concussed Labrador.
