Tracy Morgan Says He's A Prince Jokes That Rihanna Is In His Harem On 'Late Show With David Letterman' (VIDEO)

It was classic Tracy Morgan on "Late Show" (Weeknights, 11:35 p.m. ET on CBS), meaning he was a little bit all over the place. When Morgan is in his element, he's as unpredictable as they come, making it pretty easy to see where the inspiration for Tracy Jordan on "30 Rock" came from. In fact, sometimes it's not all that easy to tell the two Tracys apart.

He zoned out on Letterman several times, and revealed that he's a prince -- he's not -- and that Rihanna is actually back at his place and a member of her harem -- she's not. Morgan also addressed the fainting incident at Sundance when he was hospitalized, maintaining that it had to do with the higher altitude ... sort of.

"When you’re A-list and you’re way up there, the altitude gets thin," he explained. "The only [other] person was Michael Jackson, that got to that height."

Tracy Morgan as Tracy Jordan can be seen Thursdays at 8:30 p.m. ET on NBC, while "Late Show" airs weeknights at 11:35 p.m. ET on CBS.
