David Letterman may have been forced to admit to a string of affairs live on air by a blackmailing producer, but the Late Show host has said no one is to blame for the fallout but himself.

The talk show host has opened up about his indiscretions with female employees and how they rocked television - and his marriage - in a tell-all interview with Oprah Winfrey.

In October 2009, the host made a shocking on-air revelation on the Late Show that he had cheated on his wife, Regina Lasko, whom he had only married that March.

He made the confession after becoming the victim of an extortion plot concocted by a then-CBS producer, Robert Halderman, who demanded $2 million in exchange for his silence over the affairs.
