Jimmy Fallon reached into his Saturday Night Live
pocket and pulled out a big trick: Music superstar Justin Timberlake
will be a guest on Fallon's very first Late Night
show, PEOPLE has learned exclusively.
Fallon, the former SNL
star who's taking the reigns of NBC's talk show from Conan O'Brien beginning March 2, famously costarred with Timberlake in the classic SNL
skit, "The Barry Gibbs Talk Show."
Fallon previously announced another guest for his debut behind the desk: Robert DeNiro. "I thought it would be kind of good to have my first guy be probably one of the toughest people you could interview," Fallon said
during a Feb. 19 phone call with press.
PEOPLE has also confirmed that Fallon booked music act Clap Your Hands Say Yeah for his March 4 show, and Gossip Girl
hottie Chace Crawford for March 6.
Timberlake's rep could not be reached for comment.
