Publicly, David Letterman has received the full support of the high-ups at CBS. Behind the scenes, however, execs are bit more skittish. Sources inside the company told the New York Times on Friday that Letterman could possibly lose their backing if more damning information about his flings with employees come to light.

Letterman has a long history of dating young women that work for his production company, Worldwide Pants, one longtime associate of his told the Times. He carried on a longtime relationship with a head writer on 'Late Night' and he is said to have been linked to at least two previous assistants, including Stephanie Birkitt, who is at the center of the alleged extortion plot against the star.

However, CBS and Letterman announced on Friday that all affairs took place before he married his longtime girlfriend, Regina Lasko, in March.
