The reality competition show 'Fashion Star' isn't even close to premiering on NBC yet, but Wendy Williams has already started gossiping about it. Back for a new season of 'The Wendy Williams Show' (weekdays, syndicated on CBS), Williams talked about potential problems between 'Fashion Star' mentors Nicole Richie and Jessica Simpson.

"You're not going to see this show until, it's like a mid-season replacement, somewhere around later in the winter," said Williams. "But Nicole's reps are denying that they're having any fights at all. Sources told US Magazine that there is friction, however, on the set. They say that Nicole thinks that Jessica doesn't know high fashion."

Nicole Richie has been a reality star, TV personality and author, but mentor? That may take some getting used to. Richie will be a fashion mentor on NBC's new show 'Fashion Star,' which has a twist to differentiate it from other fashion design reality competitions. Richie previewed the show Wednesday on 'Access Hollywood Live' (weekdays, syndicated on NBC).

On 'Fashion Star,' fourteen designers will compete to design collections for three retailers -- Macy's, H&M, and Saks. But unlike many shows where designers create high-end fashion garments more suited to a Siberian runway, the clothes have to be wearable and desirable to the general public. "Let's say H&M buys a designers collection for that week -- you can go to H&M and buy it the next day," Richie said.

This is no joke: Jason Priestley and 'Arrested Development' star Tony Hale are heading to USA Network's 'Psych.'

According to Entertainment Weekly, 'Beverly Hills, 90210' veteran Priestley will play a biker con man who attempts to pull off a job at the same resort where Shawn (James Roday) is vacationing.

Hale will play an imports and exports businessman who interacts with Shawn and Juliet (Maggie Lawson) while they're on a romantic weekend away.
