She did a good job, I especially liked her "Hello Heartbreak" performance.
Random: Is it me or Michelle shouldnt have covered a "Rihanna" song, not that theres anything wrong with Rihanna, shes great at what she does, its just that, it should be the other way around or not done at all. Its just like her covering Beyonce's "Crazy in Love", quite degrading I think.
Anyhoo, Hello Heartbreak is under the cut*
