Lady Gaga and Justin Timberlake Booked For ‘The Tonight Show’ with Fallon

Lady Gaga and Justin Timberlake will be celebrating the launch of "The Tonight Show starring Jimmy Fallon" next week.

Following U2, who will assist Fallon with the premiere episode on Feb. 17, Gaga, Timberlake, Tim McGraw and Arcade Fire will appear.

All acts will be performing on the revamped show, which comes just days after Jay Leno signed off the air for good, making room for the planned revamp of "The Tonight Show" with Jimmy Fallon.

Additional acts are to be announced later this month.

Non musical guests include First Lady Michelle Obama, Will Smith, Jerry Seinfeld, Bradley Cooper and Will Ferrell.
