In the fame business, Linday Lohan is the heir apparent for Britney Spears. Lohan has been in show business since age four, and at age 18, she's already starred in flotsam and jetsam like "Parent Trap," "Mean Girls," and "Freaky Friday."

In "Freaky Friday," she actually sang -- and played guitar -- so you know a album debut was just an agent phone call away. Lohan, who released her debut album late 2004, Speak saw chart success with the song "Rumors." And now -- proving she's a least a flash in the pan, if not a true semi-famous person -- her second video/tune hits the airwaves.

The video starts a little downbeat, with Lohan strolling meaningfully down a suburban street as leaves fall dolefully. She gazes into her boyfriend's house, then indulges in saucy make-out scenes, which cut to scenes of her band performing and, for some reason, kids at a pool party. The thing has "hit" written all over it.

This, of course, makes Hilary Duff very upset. Duff, who owned the teen pop diva market until Lindsay Lohan was created in the laboratory, might lose market share to the new "it" girl. Lohan manages to be sexy but essentially wholesome, where Duff is just, well, wholesome.

Hilary Duff, we can only assume, has a small voodoo doll of Lindsay Lohan, and is piercing it with pins at this very moment. But Lindsay Lohan has a large poster of Hilary that she's throwing darts at. However, they can both relax: the winner will be decided by corporate marketing budget, not anything the performers' themselves do. And, with all those products to endorse, there's room for both.
