George Clooney to be Stephen Colbert's first 'Late Show' guest

NEW YORK, Aug. 7 (UPI) -- Stephen Colbert announced Friday that his first Late Show guest will be actor George Clooney.

After being one of Colbert's final guests on The Colbert Report before ending late last year, Clooney will reunite with the David Letterman replacement on Sept. 8.

"George Clooney will be my first-ever #LSSC guest on September 8th! Could one of you let him know?" Colbert tweeted Friday morning.

The announcement comes just a day after fellow nighttime TV host Jon Stewart signed off from The Daily Show after a 16 year run. Colbert visited the set during the finale to deliver a heartfelt goodbye to his friend and contemporary:

"You were infuriatingly good at your job," Colbert said in a seemingly candid speech. "All of us who were lucky enough to work with you for 16 years are better at our jobs because we go to watch you do yours."
