Gwen Sebastian and Erin Willett battled each other in The Voice Season 2, Battle Round 3 on March 19, 2012. 

The members of Team Blake Shelton sang "We Belong" by Pat Benatar, after being mentored Miranda Lambert and Kelly Clarkson.

While Christina Aguilera and Adam Levine liked Erin's style and the richness of her voice, Cee Lo Green favored Gwen for her final notes. 

In the end, Blake chose Erin, to see what else she had up her sleeve, eliminating Gwen.
