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.

MTV is preparing a spin-off of its popular reality series 'Teen Mom.' The network has reportedly already set its cast and done some location shooting.

This should come as no surprise since 'Teen Mom,' itself a spin-off of '16 and Pregnant,' averaged 2.8 million viewers. And the show -- chronicling the lives of teen mothers Amber, Maci [at right], Catelynn and Farrah -- attracted close to 6 million to its finale. '16 and Pregnant,' which returns for a new season Oct. 26, averaged 3 million viewers.

According to the New York Post, the series will be separate from both shows, but feature cast members from both.

"We're always exploring new production ideas, but can't confirm anything at this time," an MTV spokeswoman told the Post.

Now that the fall shows are drying up, those midseason replacements are becoming more and more essential. Zap2It tells us CBS has shifted the premieres of The Captain and The New Adventures of Old Christine from January 28 to February 4 (so as to not compete with the State of the Union Address). And furthermore, The Captain has been redubbed Welcome to the Captain.

In this new series, Fran Kranz plays a young man who moves into a legendary Hollywood apartment complex. His new neighbors are played by the likes of Raquel Welch, Jeffrey Tambor, Chris Klein and more. Which I guess means it's a show about a bunch of wacky neighbors, as opposed to the requisite one.
