LOS ANGELES (AP) — A former writer for late-night TV host David Letterman said she quit his NBC talk show in part because of alleged sexual favoritism and a hostile work environment.

Nell Scovell, writing for Vanity Fair online Tuesday, said she had no intention of filing a lawsuit and wasn't seeking revenge.

"I wanted to shine a light on gender inequality in that particular workplace," Scovell, who went on to a successful Hollywood career, said in a telephone interview.

In the Vanity Fair article, Scovell said Letterman didn't "hit on her" during her roughly five-month stint with NBC's "Late Night with David Letterman" in 1990.

"Did he pay me enough extra attention that it was noted by another writer? Yes. Was I aware of rumors that Dave was having sexual relationships with female staffers? Yes," Scovell wrote.

Other high-level male employees were having sexual relationships with female staffers as well, she alleges, and the women gained professional benefits from those relationships.

"Did that make me feel demeaned? Completely. Did I say anything at the time? Sadly, no," wrote Scovell, whose credits include writing for the series "Coach" and "Monk" and creating "Sabrina, the Teenage Witch." She's also produced and directed.

Letterman, who moved to CBS in 1993 for "Late Show," has admitted to workplace affairs that led to an alleged blackmail plot.
