Channel Surfing: Kara DioGuardi Leaves Idol, Treadstone Heads to CBS, Ashmore Twins Land Fringe, Glee, and More

Welcome to your Tuesday morning television briefing. With the holiday weekend having just wrapped, no one was breaking too much news. Which isn't to say that there are no key television-based headlines, because, well, there are. Let's get to it.

It's official: Kara DioGuardi will not be returning to FOX's American Idol this season. The singer-songwriter joined the judges table two years ago and FOX has now confirmed the long-gestating rumors that DioGuardi would not be returning for another season of the musical competition series. "I felt like I won the lottery when I joined American Idol two years ago, but I feel like now is the best time to leave IDOL," said DioGuardi in an official statement. "I am very proud to have been associated with American Idol - it has truly been an amazing experience. I am grateful to FOX, FremantleMedia and 19 Entertainment, as well as the cast, crew and contestants, for all they have given to me. I look forward to my next challenge, and want to thank everyone who has supported me. All the best to everyone on Season 10!" Idol creator and executive producer Simon Fuller had this to say about DioGuardi's departure: "Kara is one of the world's best songwriters. She has been passionate and committed to Idol over the last two seasons. I will miss having her on the show, but I look forward to working with her in music for many years to come."

Shawn and Aaron Ashmore--the twin actors known for their roles in the X-Men film franchise, Smallville, and Veronica Mars--are set to appear in Season Three of FOX's Fringe this fall. The duo are set to guest star in an episode slated to air in November and have turned down other invitations to play opposite each other in the past. "It's usually because the stuff that comes along is kind of hokey," Shawn Ashmore told Chicago Now. "But I think the quality of Fringe is really high and the episode is done well and our characters are intelligent. We're going to have some fun." No word immediately on just who or what they'll be playing but it's safe to say that twins will play into the equation in some capacity. (via Digital Spy)

"I discover Will's chewing his teeth, so the other day I had, like, four fingers in Matthew Morrison's mouth."

The Office isn't going anywhere, executive producer Paul Lieberstein told E! Online's Megan Masters on Friday... and indicated that there could be an Office movie. [Editor: for the love of all things holy, no.] "There's been no talk at any point of The Office ending," Lieberstein told Masters. "Maybe when the series is done we'd do an Office movie. I'd be up for that... But they're all such big movie stars now, I don't know if we could afford them on set." Lieberstein also advised fans to stick with the series even after Steve Carell leaves at the end of this upcoming season. "This will definitely change the dynamic [of the show]," said Lieberstein. "And we can't just replace Steve because I think that would lead to failure. We have to do something different. This show is really about office life, which so many people live. And changing it up a little will be welcome to the fans. Steve feels he's played almost everything he can with Michael Scott. There isn't a lot of new territory for him to discover. And if he's feeling that, fans must be, at a certain level, feeling that too—it's an opportunity to reinvent The Office." (E! Online's Watch with Kristin)
