Zac Efron  planted a kiss on Vanessa Hudgens  as they arrived at LAX together on Friday afternoon. Your favorite couple who met on set  were away following all of Zac's hard work promoting Me and Orson Welles , and now the duo is back home in California. There wasn't much rest in sight for Zac though, because he was off on Saturday for a trip to the gym to keep his famous abs  in tip-top shape.

Hopefully Zac managed to slip away to pick up a special something for his girlfriend, as today is her 21st birthday!
