Zac Efron & Vanessa Hudgens Share Clothes

High School Musical stars Zac Efron and Vanessa Hudgens share more than on-screen time together — they share each other’s clothes!

Zac, 19, fielded audience questions about musical theater at a Q&A session during the 2007 Junior Theatre Festival in January down in Atlanta, Georgia.

Vanessa, 18, wore Zac’s same blue-and-red striped shirt on Monday while out and about the Recoleta neighborhood in Buenos Aires, Argentina.

Zanessa were spotted frolicking along the beaches of Hawaii earlier this month (pictures have since been removed).

Next weekend, the stars of High School Musical 2 are scheduled to take center stage at Buenos Aires’ biggest stadium - The River Plate Soccer Stadium.
