All week long, we're celebrating "The New Class," Hollywood's latest group of up-and-coming actors and actresses on the cusp of graduating to greatness. Tune in every day this week for exclusive interviews with these pending graduates and your chance to vote for the student body president - the one you think holds the brightest future in the industry.

Even nice girls have a mean streak. Take Lily Collins, for instance: the young actress, with credits like the heart-warming "The Blind Side" and the pulse-pounding "Abduction" to her name, is just as likely to bring you baked goods on a bad day as she is to kick bad guy butt when the need arises.

That's why we've bestowed Lily with the title of The Ass-Kicking Girl Next Door as part of the New Class, and we think her resume of past and future credits more than speaks to her sweetheart side and her badass streak.
