The Foo Fighters frontman will help Fallon deliver Monday's monologue, interview guests Jim Jeffries and Blake Shelton and participate in Tonight Show sketches. Monday won't be Grohl's first time hosting a late-night talk show. In 2017, he dressed up as David Letterman filling in for Jimmy Kimmel for a Halloween episode of Jimmy Kimmel Live!
