MATT SNUBBED FOR ZAC

MATTHEW PERRY was mobbed by pretty fans at an LA burger bistro – then got dropped like a bag of cold fries when “High School Musical” heartthrob ZAC EFRON suddenly strolled in. The two stars had been working nearby on their “Seventeen Again” movie and decided to lunch together. “Friends” star Matt arrived fi rst, was immediately surrounded by young cuties, and posed happily for pics – until the fan-addicts let out blood-curdling screams, dumped Matt and surrounded Zac, who scribbled autographs as his co-star dragged his buns and burger to a table.
