Where you've seen her before: "Bridesmaids," "Bachelorette"
Breakout Role: "Pitch Perfect"
Why: The Aussie comedian has been stealing scenes in Hollywood comedies over the last couple of years, and she seems like a perfect late night talk show guest, but "Pitch Perfect" -- which is off to a smashing start at the box office in limited release -- will likely propel her to a new level of stardom. She'll soon be seen in Michael Bay's "small" comedy "Pain & Gain," alongside Mark Wahlberg and Dwayne "The Rock" Johnson.
