Sirius' Raw Dog channel (ch 104) is covering the "Star Wars Celebration IV" at the Los Angeles Convention Center, which started today (May 24th) at 12-noon ET and will continue through Tuesday, May 29th.

Star Wars Celebration IV is the biggest Star Wars party ever.  Thirty years ago, Star Wars opened in theaters and took audiences on a groundbreaking journey to a galaxy far, far away. It instantly seized the public's imagination, and three decades later still claims that grasp. The event brings the best of the Star Wars universe together in one place for a weekend that’s designed by fans for fans.

Coverage begins with reports from today’s "fan club only" events and includes a full weekend of reports that will include droid building, costume contests, Jedi training, the “Stormtrooper Olympics” and sneak peeks at the all-Star Wars episodes of Family Guy and Robot Chicken.

Sirius is also staging a final battle between Darth Vader and Yoda for the best two characters as voted by fans in Sirius’ "Duel of Fates." The winner will be announced at 12 noon ET on Tuesday.

Judith Regan and her show on Sirius are undergoing some changes.

First she's been telling friends that she's going into the art business, according to a RADAR source. RADAR also notes that Judith's public profile has been diminishing ever since her OJ Simpson book created controversy in the headlines.

Her weekly two-hour talk show on Sirius Stars (ch 102) was recently bumped from its regular daytime slot and now only airs twice between midnight and 4am ET.

Could Regan eventually get phased out? One could only hope.

People are staying busy over at Sirius' Martha Stewart Living Radio (ch 112). They've just launched "At Martha's Table," a new series that features Martha Stewart conducting live one-on-one interviews with influential tastemakers.

For the debut broadcast of "At Martha's Table," Martha will sit down with internationally acclaimed chef and restaurateur Jean-Georges Vongerichten. The show will air tomorrow, May 23rd from 7 - 8pm ET. Martha and Jean-Georges will discuss his life, passions, and inspirations, and take calls from listeners. Jean-Georges will also share tips for the home cook.

Jean-Georges Vongerichten holds a total of sixteen stars from The New York Times for his New York City restaurants JoJo, Vong, Jean Georges, Mercer Kitchen, 66, Spice Market and Perry St. He has also received a total of 5 Michelin stars for Jean Georges, Vong, and Perry St. He currently has 19 restaurants in locations around the globe, including London, Paris, Shanghai, the Bahamas, Chicago, Minneapolis, and Bora Bora.

This is the third programming change to Martha's Sirius channel in the past few weeks. In late April Sirius debuted the "Morning Living" show, and a few days ago Sirius announced a new block of pet-centric programming.

Sirius' Martha Stewart Living Radio (ch 112) has expanded their format of cooking, homekeeping and gardening content, to offer a block of pet-centric programming.

From advice from Martha's personal vet, to expert tips and the latest trends in behavioral training - and much more - animal lovers can tune in to a variety of live call-in shows about how to care for their favorite furry friends (like that cute little doggie 'Chester').

The new block of pet shows airs Monday - Friday nights at 8pm ET exclusively on Martha Stewart Living Radio.

Sirius' Maxim Radio (ch 108) is celebrating Maxim magazine's annual list of the 100 sexiest women in the world, the 2007 Maxim Hot 100. The 2007 Maxim Hot 100 Countdown is airing all day today as a four-hour countdown show, and tomorrow Maxim Radio will broadcast live red carpet coverage of the star-studded Maxim Hot 100 party.

After two years on top, Eva Longoria has passed the crown off to Lindsay Lohan, who claims the top spot of the Maxim Hot 100 for the first time. Joining Lohan on the Top 10 list are Jessica Alba, Scarlett Johansson, Christina Aguilera, Jessica Biel, Ali Larter, Eva Mendes, Rihanna, Eva Longoria and Fergie.

The 2007 Maxim Hot 100 Countdown is an in-depth look at the entire list, featuring Maxim Editor-in-Chief Jimmy Jellinek live in-studio along with the Maxim editors and photographers who put the list together. They will reveal behind-the-scenes stories of how the beauties are selected. The broadcast will also feature interviews with past Hot 100 honorees such as Eva Mendes, Avril Lavigne and Fergie. Also on hand will be a panel of “regular guys” standing by to give their instant reaction to the list.

Tomorrow night (May 16th), Maxim Radio’s afternoon duo Covino & Rich will be at the Hot 100 party in New York City for an exclusive live broadcast from the red carpet starting at 9pm ET. Covino & Rich will interview celebrities and provide insider access to one of the hottest parties of the year.

Sirius is broadcasting the COSMO Radio Confessathon - tomorrow, May 5th starting at 2pm ET - on Sirius' Cosmo Radio (ch 111).

The special will feature 500 real confessions based on the magazine's popular "Confessions" and "Guy Confessions" columns.

From dating disasters and sex snafus (grrr) to bad office behavior (grrr) and the shocking things people say behind their friends' backs (grrr?), hear the hilarious and scandalous (grrr) messages left on COSMO Radio's voicemail.

COSMO Radio will also give men and women the chance to spill their naughtiest secrets live on air during the broadcast. (Grrr.)

But wait, there's more.

The COSMO Radio Confessathon will also include confessions from people whose jobs and lives make them privy to some extra juicy scoop-like a Miami socialite who regularly parties until sunrise, a celebrity trainer who knows what the stars really do to get red-carpet ready, and two backup dancers who have performed with some of the biggest acts in pop music.

Tune in tomorrow at 2pm ET, and stay tuned in, because the Confessathon won't end until all the confessions have aired.
