Craig Ferguson, always the goodwill ambassador. CBS’ late night host — who once famously donned a Mickey Mouse glove on The Late Late Show and waved to Jimmy Fallon, who graciously waved back with one of his own on Late Night — will welcome Jay Leno for the first time later this month.

Ferguson invited Leno simply because he was deemed to be a good guest, says one insider. And it’s not like the two haven’t sat opposite each other in late night: Ferguson appeared on The Tonight Show last year to promote Disney’s Winnie The Pooh movie, Deadline says.

CBS’ late-night star should be in a particularly good mood these days, now that he’s occupying bigger and better digs on the network’s TV City lot in Los Angeles. He took over a different sound stage in August.
