NEW YORK (AP) - Jimmy Fallon is premiering his new show with a bang.
NBC announced Monday that Will Smith will appear on the Feb. 17 debut of "The Tonight Show Starring Jimmy Fallon." U2 will perform.
Justin Timberlake will close out the week, which will also include appearances by first lady Michelle Obama, Will Ferrell, Bradley Cooper, Kristen Wiig and Jerry Seinfeld.
Lady Gaga, Arcade Fire and Tim McGraw will perform during the week.
The first four episodes of Fallon's new show will air at midnight following the Sochi Winter Olympics. Its regular time slot is 11:35 p.m. Eastern.
Fallon replaces Jay Leno, who hosted "The Tonight Show" for 22 years. "Saturday Night Live" alum Seth Meyers is Fallon's successor; his "Late Night" show debuts Feb. 24.
