Zac Efron and Danielle Panabaker: Does Vanessa Know?

Zac Efron (and his increasingly Katie Holmes-esque hair) was photographed out with Friday the 13th actress Danielle Panabaker last night at Hugos restaurant in West Hollywood.

Zac has a girlfriend (his High School Musical co-star and Oscars musical-number partner Vanessa Hudgens), so this must be some sort of business meeting.

Or a friends thing? Guys can have gorgeous female friends, right?

Besides, a paparazzi magnet like Zac would know better than to take his side dish out in public if that was what was going on.

Danielle might want to watch out. If Vanessa catches her trying to steal Zac, she’ll probably bust out a wrath 1,000 times worse than anything Jason Voorhees did to her in the Friday the 13th remake.

Besides, shouldn’t she be busy reminding Shark co-star James Woods, 61, to take his Metamucil, so to speak?
