NBC Reportedly Threatens Celebs Wanting to Appear on Jimmy Fallon

NBC is threatening potential 'Tonight Show' guests, according to TMZ, saying they won't have a chance to sit down with Jimmy Fallon if they appear on CBS or ABC shows. As John Basedow (@JohnBasedow) reports, the former 'Saturday Night Live' star, who's already had major A-Listers Justin Timberlake, Will Smith and First Lady Michelle Obama on his late night show, is doing so well in ratings that NBC reportedly feels justified in these supposed strong arm tactics.
