Zac + Vanessa + Mexico = Happiness!

Zac Efron and main squeeze Vanessa Hudgens return from Mexico looking happy and smiling ear to ear at LAX airport in Los Angeles on Friday.

Look at little V hiding behind her main man Zac!

In case you missed it, the Disney darlings were recently at the HSM3 premiere in Mexico City on Thursday.

Wonder where Zanessa will be heading to celebrate Halloween tonight!

WHAT DO YOU THINK Zac and Vanessa will be dressing up tonight for Halloween?
