From the wildly popular High School Musical to the upcoming Grease: Live production, Vanessa Hudgens knows a thing or two about hanging out in high school halls - but funny enough, the star was homeschooled!<br />The actress joked about her tendency to take high school roles and opened up about her upcoming role as Betty Rizzo in the live telecast of the famous film.<br />As for whether she's nervous about the live element of the show, Hudgens admitted she didn't start feeling the pressure until she took a tumble during rehearsal.<br />"We were doing 'Sandra Dee' and I stepped on a bench in front of the bed and it flipped and I just fell on my butt so hard," she recalled.<br />But the best part of Hudgens' interview was probably when she was discussing Didi Conn , the actress who played Frenchie in the original movie and who will star in the live production as well.
