'Charlie St. Cloud' premiere: Zac Efron, Vanessa Hudgens are STILL adorable

zac-efron-vanessa-hudgens.jpgIt's been a few years since they were together in the "High School Musical" films. But Zac Efron and his girlfriend Vanessa Hudgens are still going strong and are still the cutest darn couple in Hollywood.

What makes their relationship work when so many other Young Hollywood hookups fail? We haven't a clue, sorry. If we did, we'd bottle it and sell it on Robertson Blvd, from a stand right outside the Ivy.

All we know is that at Tuesday (July 20) night's LA premiere of "Charlie St. Cloud," Vanessa was golden in a sleeveless Reem Acra satin minidress with Jimmy Choo metallic heels and a Ferragamo bag.
