ABC's new one-hour comedy, 'GCB' -- starring Kristin Chenoweth and Annie Potts -- has lined up two superstar guest appearances that will surely get people talking.

Singer-song writer Sheryl Crow will guest star as herself in the series' fifth episode, reports TV Guide. "Sheryl is great," 'GCB' creator, Robert Harling, told TV Guide. "She is the guest star at the church fundraiser. It was fantastic working with her. She's a great actress."

Funny lady Sandra Bernhard will also make a guest appearance in the show, but for now, the details are top secret. "It's a big surprise," Harling reveals.

If you missed the big, um, event last week, Harry Smith had a colonoscopy live on 'The CBS Early Show.' So of course David Letterman had to have him come on last night and do the Top Ten List for the "Top Ten Things Going Through Harry Smith's Mind During His Televised Colonoscopy."

Harry Smith wasn't on The CBS Early Show this morning. Well, he was, but via webcam from his house. Why? He may have H1N1! But he got to appear on the show and wear a comfy t-shirt!

By the way, H1N1 & Harry is a new show this fall on CBS.

I hope Hannah Storm enjoyed sleeping late since she's been off the CBS Early Show because her new gig will be on the AM shift once again. And she'll be back talking sports. ESPN is going to announce tomorrow that Hannah Storm will anchor a new, revamped SportsCenter morning edition. SportsCenter is already on every morning, so you have to assume that by adding Storm to the mix, the folks at Disney (ESPN's parent company) are looking to pump up the old format and maybe bring in some new viewers -- like maybe those who used to watch Hannah on CBS.

Of course, there's already two other competing morning shows on the ESPN family of channels, Mike & Mike in the Morning which stars Mike Greenberg and Mike Golic, and First Take (formerly known as Cold Pizza) with Jay Crawford and Dana Jacobson.

Wow, here's something that was COMPLETELY UNEXPECTED.

Judge Larry Seidlin, who presided over the Anna Nicole hearing/circus last week, might get a regular spot on CBS' Saturday Early Show. One of the show's producers, Michael Rosen, sent Judge Seidlin a letter the other day (obtained by The Sun-Sentinel), saying that they want to hire him for a new segment on the show:

"I have been extremely impressed by your compassion in the Anna Nicole case and I would love to discuss with you the idea of being our judge on a new segment, `Morning Justice.' It would be a semi-regular segment in which you would resolve the ethical and legal questions of our viewers who send in the issues troubling them."
