'Today' host Hoda Kotb is getting the cocktail shaker ready for Jimmy Fallon, who is guest co-hosting the show's fourth hour with her tomorrow, Jan. 13.

"I hear he's already placed his drink order," Kotb tells PopEater. "I can officially say that the 'Today' show will never be the same again, ever. Jimmy Fallon at the anchor desk with me? Can you imagine? I cannot wait -- so buckle up!"
