Today's taping of The Tonight Show was canceled, after host Jay Leno fell ill.
After complaining he didn't feel well, Jay headed to the hospital. He wasn't taken by ambulance, but was either driven by a member of his staff or drove himself. He is currently being kept for observation
We'll let you know when we have more info...
UPDATE: Though Jay is currently still in the hospital, his peeps say he's doing okay.
"Jay Leno is doing just fine," an NBC rep told UsMagazine.com. "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."
