Sporting her trademark snotty sneer, “90210” retread SHANNEN DOHERTY showed up at a beach party at the pad of a top TV producer, and immediately was overheard bitching to a femme friend that the “only celebrity” present was ex-“Falcon Crest”/newbie reality star LORENZO LAMAS.

Storming out the door after less than 10 minutes, Shannen snarked: “I’m really sorry…I thought this was going to be an A-list party, but I guess I’m the biggest name here.”

Question for Cranky Skank: How did a “big name” like you end up starring in the upcoming flick “The Beautiful Outsiders” with F-listers COREY FELDMAN and CAMERON DOUGLAS, druggie son of MICHAEL DOUGLAS – who cops just busted for allegedly dealing killer crystal meth?
