Cassadee Pope once again shined on The Voice tonight. Pope took on Avril Lavigne's hit song "My Happy Ending" for the first live show of the season. She literally could not have chosen a better number. This not only let her show off her whole rocker side but her incredible vocals as well. We have no doubt that Pope will go far in this competition. Check out her performance of "My Happy Ending" from tonight's episode of The Voice below:
