This actress/singer provides examples of:
- Stylistic Suck: Her deliberately unbearable singing in 'Christmas Caroling w/ Brittany Snow'. As evidenced by Pitch Perfect and her one song in Hairspray she is actually a pretty good singer.
- The '60s: Has twice starred in a movie/TV show set in the 1960s (American Dreams and Hairspray).
