"Starbucks is the best place for star-spotting," said Tara Williams, a 23-year-old former Starbucks barista in Los Angeles. "Celebs are always on the go, so they love their drink to go."

Stars are also leading the way in the complicated concoction craze. Light and sweet? Way too boring for today's java junkies.

"Reese Witherspoon likes a grande almond strong soy latte, Mary-Kate Olsen has a venti sugar-free vanilla skim latte, Nicole Kidman orders a triple grande skim wet cappuccino, Renee Zellweger gets a grande extra hot vanilla latte with cinnamon and Katie Holmes has a half-caf grande soy latte," Williams said.

So much for a cup o'joe, regular.

According to the Web site starbucksgossip.typepad.com, where employees dish the dirt on star-studded orders, Britney Spears goes "Crazy" for a venti extra caramel frappuccino, Elijah Wood prefers a quad espresso over ice in a venti cup and Ricky Martin's "Cup of Life" is a four-shot, non-fat, sugar-free espresso venti vanilla latte.

They're not alone. Mike Meyers digs a double short breve cappuccino, Montel Williams talks up the raspberry soy white mochas and John Travolta's "Phenomenon" is a double espresso.
