"Tonight" show host Jay Leno is reported to being doing well after he checked himself into a hospital with an undisclosed illness, the Associated Press reported.
Leno's publicist, Dick Guttman, said the comedian left his office at NBC's studios about midday Thursday and checked himself into the hospital for observation. Guttman didn't reveal the hospital or what symptoms Leno experienced, but did say the illness was "mild."
The publicist also said Leno kept working after he went to the hospital, writing jokes and making phone calls, the AP reported.
"Jay Leno is doing just fine," NBC spokeswoman Tracy St. Pierre said in a statement. "He was kidding around with the hospital staff and running his monologue jokes by the doctors and the nurses. He's expected back to work on Monday."
