Zac Efron is a Shy Guy

Zac Efron and his two new basketball buddies leave basketball practice together in Hollywood on Friday.

The High School Musical star apparently sings a different tune when he’s not being showered with flowers from paparazzi.

Zac, 20, shied away from photographers this time around, hiding his face behind a basketball. Why so shy, guy?
