[UPDATE BELOW] Fans of The Colbert Report got an unwelcome surprise last night when the new episode of The Daily Show was followed by a rerun of the Report. And fans who expected to watch the show's taping in person were also surprised when they received this email that went out to ticketholders: "Due to unforeseen circumstances, we have cancelled our taping for the date of your ticket reservation, February 15, 2012." No explanation has been given.

Guests Claire Danes and Susan Cain were booked for last night and tonight but they've now been bumped. Stephen Colbert has not issued a statement about the sudden suspension, which is a first for the show. The Third Beat notes that "a last-minute cancellation is highly unusual for Comedy Central’s fake news shows. The Daily Show has suspended production last-minute due to personal reasons twice during Jon Stewart’s reign: once when his second child was born, and once when a staff member passed away suddenly."

Speaking to Politico, Comedy Central Senior VP for Communications Steve Albani confirmed the temporary suspension, but said that Comedy Central is "not providing any additional details at this time.” [Via Mediaite]

Update 3:52 p.m.:
Sources tell the Wall Street Journal that Colbert has suspended production temporarily "because of an emergency in Mr. Colbert's family." No further details were forthcoming.
