Vanessa Hudgens 'giddy about' co-star

Zac Efron who?

Vanessa Hudgens was aglow while hanging out with her good friend (and rumored new beau) Josh Hutcherson over the weekend.

After shooting “Journey 2: The Mysterious Island” in Hawaii, the co-stars were spotted walking around the LG Cinema 3D HDTV Gift Lounge before the Independent Spirit Awards on Saturday.

“Vanessa was clearly giddy about Josh – the two did not leave each other’s side once, and she couldn’t help but dance around the lounge all day,” a spy told us.

Hudgens also chatted with pal Rosario Dawson at the lounge.
