David Letterman's Other Other Woman
TMZ has obtained photos of
Holly Hester -- the woman who acknowledged she
had a relationship with
David Letterman in the early 1990s -- back when she worked as an intern for Dave.

The pics show Hester with segment producer Frank Gannon (

Hester said her relationship with Letterman lasted a year and that she was "madly in love with him."
