Vanessa Hudgens is a Tired Kitson Shopper

Vanessa Hudgens looks tired as she takes a break at the Americana Mall on Thursday afternoon in Glendale, Calif.

The 19-year-old High School Musical sweetheart is busy shopping for the holidays and preparing for her 20th birthday. Vanessa was out and about yesterday shopping and stopped at Napa Valley Grille in L.A. for lunch.

Next month, Vanessa and her on-and-off-screen lover Zac Efron will be heading to Japan to promote their film, High School Musical 3: Senior Year.
