VANESSA FUMES WHEN ZAC YAWNS

Just before filming wrapped on ZAC EFRON’s new flick, “The Death and Life of Charlie St. Cloud,” galpal VANESSA HUDGENS jetted to the Vancouver location, and the lovebirds ended up lip-and-hip-locked on a bench in Stanley Park until a giggling gaggle of eight teen girls leaped from the bushes, screaming “ZAC!”

The punk-ettes nearly pushed Vanessa off the bench as Zac, all smiles to her sulks, scribbled autographs, then shooed away the howling horde – but not before one creep-ette snatched his scarf and fled.

Zac just shrugged as Vanessa shrieked: “Aren’t you going to go after her and get it back?” Yawned Zac: “I’m not going to run after them for a scarf…it’s not worth it!”

Oooops!...WRONG ANSWER, ZAC!

Screamed furious Vanessa: “Not WORTH it? That’s the scarf I gave you for your birthday… REMEMBER!?” And off she stormed as he stuttered mega-mea culpas.
