Cable news legal expert Nancy Grace has found herself in some legal hot water of her own.

The CNN Headline News host was sued for $15 million for "not honoring an agreement to have her long-term associate, Patricia Caruso, act as executive producer of her new syndicated show 'Swift Justice,'" according to The Hollywood Reporter.

Caruso alleges that she and Grace discussed a potential new show over a lunch meeting in 2008, which then turned into 'Swift Justice.' They supposedly had a verbal agreement to work together.
