Sanjaya Hits Puberty!

Sanjy's grown some facial hair, and he wants the world to know it!

If you watched last night's J.Lo-mentored edition of "American Idol," you probably noticed Sanjy's freshly-fuzzed face. Our inside source tells TMZ that "It was all [Sanjaya's] idea."

Perhaps the little songbird is trying to address media scrutiny of his "masculinity" by adding his own bit of Tom Selleckness.

While it was a compelling attempt at butching it up, it looked to us like his face was a little dirty. Sanjy warbled a version of "Besame Mucho" (kiss me a lot) and batted his doe eyes at the swooping camera. Did the facial

hair help? You decide.
