She kissed a girl and she liked it. So did the 2.5 million Americans who downloaded Katy Perry?s breakthrough hit, keeping the pseudo-sapphic make-out session on top of the US charts for seven weeks. And no doubt pushing up the sales of cherry chapsticks.

Girl-on-girl action clearly sells. But it's not only dirty old men turned on by the cute 23-year-old's lesbian lip locking. Kids are seduced by the song's addictive sugar rush ? unsurprisingly, considering its pedigree. Written and produced by the team behind Kelly Clarkson?s biggest singles, ?I Kissed A Girl? was unlikely to fail. But the record company weren?t taking any chances ? working with all the go-to-guys on the mainstream pop-rock scene, this pop tartlet comes from the same factory that baked Avril, Pink, Britney and even Paris.

But despite the talent surrounding her ? which also includes one half of the Eurythmics and the co-writer of Bon Jovi?s biggest hits ? this daughter of two Christian pastors has something that can?t be manufactured: a sassy sense of fun. Whether boasting that she can ?belch the alphabet, just double dare me? on the tomboy-transforms-into-prom-queen title track; emasculating a boy who done her wrong on the less-than-PC ?Ur So Gay? (?I hope you hang yourself with your H&M scarf?); or pissed off with an emotionally distant guy (?You?re not a man, you?re just a mannequin?) she adds much needed spunk to the familiar girl power schtick.

Powering it all is her rock chick voice ? with traces of Alanis self doubt showing through on the two perfunctory ballads ? ensuring that the rather harmless and appropriately titled ?One Of The Boys? sits quite comfortably alongside the likes of Daughtry?s crowd-pleasing debut.
