Sean "Diddy" Combs sat down with David Letterman last night and found himself explaining the art of sexting to the 63-year-old late-night talk show host. Diddy and Letterman started things off discussing Combs' future business ventures but the conversation quickly veered toward Deadspin's discovery of some pictures Brett Favre allegedly sent to former Daily Line reporter Jenn Stager.

While Letterman seemed to be troubled by the idea of sending pics of his genitals via his cellphone, Diddy admits to be a sexter. "This is an art, and this is a relationship men and women have had since the beginning of mobile devices," Diddy explains. The entertainment mogul went on shock the host with his hilariously explicit defense of Favre's action. "Even though Brett Favre is one of the best quarterbacks of all time ... he's allowed to send a picture of his penis to um ...," Diddy explained.

Diddy and Letterman continued to snag laughs from the audience with their silly exchange. "On these new Blackberrys there's a certain angle," Diddy joklingly explains and demonstrates. "It gives you such an increase in size and width that after you take the picture, you can't help but to send it to a loved one."
