Dave Grohl -- Secret of the Hidden Valley

11/12/2008 12:20 PM PST BY TMZ STAFF
Foo Fighter Dave Grohl was thrilled TMZ finally "discovered the Valley" -- and good thing we did, because Dave's hilarious and his little "Obama" shouting daughter Violet is beyond adorable.


For the record, "The Valley" is the area located on the "other" side of the Hollywood Hills -- and not in the third circle of hell -- where the producers of "Entourage" have probably led you to believe it's located.
