HUDGENS AND TISDALE

While her boyfriend Zac Efron is in the hospital recovering from an emergency appendectomy, Vanessa Hudgens spent the day with another High School Musical co-star pal.

The 19-year-old and BFF Ashley Tisdale were spotted attending a pilates class at a local gym in Encino on Wednesday afternoon - joking and laughing on the way in. That's the way to get the right shape. Good work girls!
