US TV talk show host Jay Leno has been admitted to hospital with an undisclosed illness, forcing the star to cancel the filming of his programme for the first time in 17 years.
The presenter's publicist confirmed he had checked himself into a Los Angeles hospital for observation and said the undisclosed illness was "mild".
The undisclosure of the illness means that his condition is also "undisclosed", as is the date upon which avid viewers can expect to see his return to their screens.
Tracy St Pierre, spokeswoman for NBC's The Tonight Show said:
"Jay is doing just fine. He was kidding around with the hospital staff and running his monologue jokes by the doctors and the nurses," adding, "but we cannot disclose what he was kidding around about, nor with who."
Wolverine actor Ryan Reynolds, celebrity animal trainer Jules Sylvester and Big Bad Voodoo Daddy had been scheduled to appear as guests on the cancelled show, but the date on which they will now appear, hasn't been disclosed.
