(CNN) - Rivalry? What rivalry?
Late-night talk show hosts Jay Leno and Jimmy Fallon, who've been pitted against each other as rumors fly that NBC is mulling a changing of the guard, made light of their situation Monday night, by belting a show tune together.
"Tonight, tonight, who's going to host 'Tonight?' Is it going to be Jimmy or Jay?" the pair sang in a parody of "Tonight" from the Broadway musical "West Side Story."
The rumor mill has Fallon, 38, taking over 62-year-old Leno's job as host of NBC's "Tonight Show," and Leno has responded with pointed barbs at his employer that have seen his ratings rise.
"In the news, they say I'm replacing you, they think that I can woo, the demo," Fallon sang.
