VIDEO: Bill O'Reilly Hints He May Appear on 'Glee'

On 'The O'Reilly Factor' (weekdays, 8 PM ET on Fox News), Bill O'Reilly was critiquing a clip of Willie Geist, Ann Curry and Jenna Bush Hager dancing on 'Today' when he made a surprising revelation.

"I was on the set of 'Glee' last night," O'Reilly disclosed. "And after seeing those professionals, and that ... pretty frightening. And I want to thank all of the 'Glee' people for being so nice to us."

O'Reilly has taken shots at 'Glee' in the past, once accusing the show of indoctrinating the nation's youth with liberal values. And 'Glee' responded with an episode featuring a newsman character who seemed to be parodying O'Reilly.

That all appears to be water under the bridge. There are Twitter reports of O'Reilly being greeted warmly on the 'Glee' set, and the rumor is he will be playing one of the judges at the Regionals.

Will his be a singing judge? We can only hope.
