PASADENA, Calif. — It really is happening. If there was ever any doubt that NBC would actually go through with the restructuring of its late-night block, let this stand as hard proof:

While promoting his new position as “Tonight Show” host Sunday at the Television Critics Assn. press tour in Pasadena, Jimmy Fallon revealed the first guests of his Feb. 17 debut: Will Smith and musical guest U2.

On the flip side, Jay Leno will once more wrap his run as late-night king pin — a gig that has totaled more than two decades — on Feb. 6 with first-ever guest Billy Crystal returning to send out Leno, along with musical guest Garth Brooks.

Still not a believer? Here’s more proof: Seth Meyers, who will take over Fallon’s “Late Night” spot, announced later on Sunday that fellow “SNL” alum and NBC top dog Amy Poehler will be his first guest.
