Ashley Tisdale shows off her pearly whites in a new behind-the-scenes vid from her April Cosmo cover shoot.

The 23-year-old actress/singer dished on her passion for acting, upcoming album, Guilty Pleasure and upcoming movie, They Came from Upstairs. Check it:

On Guilty Pleasure: “My first album was a whole learning experience. It was about my fans getting to know me, as Ashley personally. So every song was something that I had been through: cheating, breakups, jealousy. This one [album], I just wanted to do more of a rock-out album.”

On her new flick, They Came From Upstairs: “It’s really fun. It’s an action comedy. My character, Bethany, is so much different from Sharpay. Bethany is older than Sharpay, she just graduated high school. She’s just so in love with her boyfriend. She’s so madly in love with him that she doesn’t know what is going on when the aliens invade at first.”

On her passion for acting: “I’m definitely passionate about acting and singing, I can’t choose. The acting is playing characters and stepping into someone else’s shoes which is so much fun. The music, is really, who I am.”
