Dave Grohl was among the many stars singing off Chelsea Handler at the end of Chelsea Lately Tuesday night.  In addition to the Foo Fighters front-man, we hear from Sammy Hagar, Avril Lavigne, Alanis Morissette, and a bunch of other people.  Gwen Stefani kicked it all off with some nice words.  In the crowd, there are tons of famous faces.

Grohl is no stranger to Chelsea Lately.  He even served as a guest host.
