Thanks to fan Starfishy2000's eagle eyes, she caught a quick clip on The Insider of Jimmy Kimmel wearing a Clay Aiken cap and posted it on The Clayboard. After seeing the post, Clayscience videoed the spot and posted a screencap along with a link of the Q&A where Jimmy wore the hat.
The event was a Q&A session with the ABC Entertainment president. An Associated Press article entitled, Kimmel, ABC get laughs out of Leno's future gig, By Lynn Elber, has all the information about the Q&A.
Yep, Jimmy's a Clay fan for sure!!
