The Magic Mike star visited David Letterman on Wednesday (June 27) night where he revealed that he has a talent for imitating McConaughey's distinctive drawl.
"All right, all right, all right," Tatum said. "I see a lot of lovely ladies in the house tonight. I like that. How you doing, Mr Letterman, you doing all right today?"
"I'm doing just fine," Letterman answered. "And now it's getting creepy."
Matt Damon previously demonstrated his knack for impersonating McConaughey on Letterman's late night show.
Tatum recently opened up about his experience shooting Magic Mike, saying that a thong is a difficult item to trust.
The Steven Soderbergh-directed film is currently being developed for Broadway.
Magic Mike is due for release on June 29 in the US and July 11 in the UK.
