Vanessa Hudgens shows off her pearly whites as she appears on The Ellen DeGeneres Show on Thursday morning (May 7).

The 20-year-old actress dished about her new movie, twitter posers and having stage freight. Check it:

On performing at the 2009 Academy Awards: “I was so frightened. I was so scared because you’re getting ready and everything seems normal and great, it’s just another awards show. Then you get there and you see the statues and I’m like, ‘Am I really here?’ Getting ready for the show, backstage, I’m freaking myself out because I’m wearing high heels and I don’t want to go out and go tripping down the stairs in front of Brad [Pitt] and Angelina [Jolie], half naked with a leotard and a top hat. It’s frightening and it’s not a situation you want to be put in. But it was still great and the most rewarding thing.”

On Twitter posers: “I don’t have one. Someone is pretending to be me on Twitter and someone told me that the person who’s trying to be me was saying that (boyfriend) Zac [Efron] got me a bowling alley. People are saying crazy things.”

On her upcoming flick, Bandslam: “It’s so much fun. She’s a lot darker and introverted. Sa5m, the 5 is silent. I actually come out with a Flying V. I get to rock out on the guitar. I learned how to play for the part. Unfortunately though, the song I do in the movie is still the only song I know how to play.”
