Dave Grohl And Kristen Bell Perform The Perfect Mash Up

Dave Grohl and Kristen Bell performed one hell of a mashup on JImmy Kimmel Live on Halloween! When you think of Kristen Bell, she strikes you as a quiet and very feminine type of woman.

She proved our assumptions wrong after her hard core duet with Dave Grohl on Halloween night! Dave Grohl definitely scored major brownie points with his daughters Violet, Ophelia and Harper after his mashup with Kristen Bell. Not only was Dave Grohl excited but Kristen was totally stoked as well to jam with the Foo Fighters frontman. You could even hear it in her voice when she stated she would LOVE to jam with him. She started off soft and sweet when she started with "Do You Want To Build A Snowman" from Frozen. Once their mashup was coming to an end is where you will see Kristen's hardcore side.
