NBC's A cappella talent competition 'The Sing-Off' returns for a new season tonight at 9PM ET. Host Nick Lachey made an appearance on 'Today' (9AM ET on NBC) to talk about the judging changes the show has made this season, and the inspiring musical atmosphere the show fosters. It's so contagious that Lachey has been working in the studio on a new project of his own.

'The Sing-Off' will have a new judges this year, as Sara Bareilles joins Ben Folds and rest of the crew. It will also have a longer season, as its moving to 16 episodes. Lachey said the new judges bring a wealth of energy, and experience, to a set that's already brimming with its own unique vibe. The show has struck such a nerve that not only is it creating A cappella groups as part of the competition, but singers are starting to form their own groups to compete for a spot in the competition.

VH1 has given the greenlight to a slate of new primetime reality series featuring music celebrities. Of course, some of those celebrities are more famous than others.

While most of the shows promise the same car accident, "can't help but stare" cringe-worthiness of the unfortunate Surreal Life, at least one or two of the promised series sound vaguely entertaining.

Here are the six titles in development:

I look forward to the day when news articles about Nick Lachey stop linking him to Jessica Simpson. I bet he feels the same. In the meantime, Nick Lachey has been cast as the lead in new sitcom pilot for The CW called, SheSaid/HeSaid. Lachey will play a bachelor named Colin who lives in New York (where else?). The rest of the cast is still being lined up for the pilot shoot, which begins in April.

Nick Lachey filed papers on friday in response to Jessica's Dec. 16th divorce filing, reserving the right to request spousal support. Jessica's divorce filing requested that she not be required to provide support but she's going to need a lawyer who can do some fancy footwork because they didn't sign a prenuptial agreement. Her success is obviously based very much on the success of their show, Newlyweds: Nick & Jessica on MTV. Jessica made more than $30 million last year.
