Craig Ferguson claimed this singer was his worst Late Late Show guest

Craig Ferguson was charisma incarnate during his tenure on The Late Late Show. He may not have been as irreverent as David Letterman or as beloved as Conan O'Brien, but those in the know, knew that Ferguson was the real deal.

He seemingly had chemistry with every guest who went on his show. Well, most every guest. He went on Watch What Happens with Andy Cohen towards the end of his tenure in 2014, and admitted a lone instance in which he struggled with a guest. He told Andy Cohen that he it was the worst encounter he had on The Late Late Show, but admits he played a role in things going so poorly.

Ferguson cited Macy Gray as his worst guest

The guest in question was R&B singer Macy Gray. She appeared on The Late Late Show in 2005, which was the first season in which Ferguson served as host. He told Andy Cohen that the singer didn't really feel like being asked questions on TV that particular night:

"I think she was in a bad mood that night."

Ferguson noted that he was still inexperienced behind the desk, and felt that he didn't know how to navigate the situation once he realized Gray was disinterested. "I think it was just- and I was very new, like couldn't handle it, you know," he explained. "But now I think it'd be okay."

Ferguson claims he was partially to blame

The Late Late Show host also asserted that he doesn't have any ill will towards Macy Gray, nor does he think that she's a "bad person" for having the interview go awkwardly. This is a cordial instance of a talk show host addressing their least favorite guest.

Others, like Jon Stewart or Conan O'Brien, felt their least favorite guests were being purposely difficult or antagonistic. It's a credit to Ferguson that he felt the need to identify his own role in the interview, and probably a reason why he eventually became so skillful with his guests later on.
