GREG DETHRONES LATE-NIGHT KINGS

Funnymen plot to wreck FOX upstart

CONSERVATIVE cutup Greg Gutfeld's claimed the crown as late-night TV's king - and his panicked talk show rivals are now plotting to torpedo the FOX News comic by exposing his darkest secrets, sources spill.

Gutfeld soared to the top of the chatfest heap last month with an average 2.19 million viewers, surpassing The Late Show with Stephen Colbert, which drew 2.16 million. Greg's broadcast also utterly crushed Jimmy Fallon's floundering Tonight Show, which notched a 1.34 million audience, and Jimmy Kimmel Live! which scored a scant 1.14 million.

"Gutfeld is now Enemy No. 1 as far as the other three are concerned," dishes an industry insider.

"Greg's laughing his head off and bragging he's the new king of TV. But the old guard isn't going to sit back and take this!"
