Jessica Simpson is the queen of the schoolgirl crush. Whenever she's dating a new man, she shouts about him from the mountaintops (Twitter and magazine covers). She takes silly photos of herself with her beau and shares them with the world. And again and again, she professes her love for her boyfriend, whether it's Tony Romo or John Mayer or Billy Corgan or her current flame Eric Johnson or (insert future guy's name here). And we root for her because we want our favorite ditzy blonde to be happy. We believe her, too, sort of -- until the relationship crumbles.

You can't fault the 30-year-old singer for her unwavering optimism. What Jess suffers from is a common ailment, one that claims countless victims in and out of Hollywood. Simpson, it seems, is in love with love.
