Foo Fighter frontman Dave Grohl guest hosted for Jimmy Kimmel Live and had Kristen Bell as a guest. Dave talks to Kristen about how his daughters would think it was the coolest thing if he got to jam out with her, and they proceded to do so, and ended up doing a Frozen/Metallica mashup that you need to see. Check it out its pretty incredible.
also huge props for the incredible costumes.
