Stephen Colbert continues to show he's a class act.

A photo of the Comedy Central star posing with a young girl on the set of his 'Colbert Report' has popped up on Reddit along with this explanation:

After our dad died of cancer, my sister sent Colbert a letter since they watched the show together every night. He invited her to the studio and this happened!!"

It's the latest instance of Colbert letting down his guard for the public. Earlier this month, he gave a moving tribute to his mother, who recently passed away.

He may be a funnyman, but Colbert clearly has heart, as well. Way to go!
