According to The Hollywood Reporter, MyNetwork is considering scrapping its current all-telenovela programming. The network is a Fox creation to keep WB/UPN affiliates alive after the networks merged to create The CW. MyNetwork debuted in September and it airs thirteen hours of dramas, five days a week, with recaps on Saturdays. The first two telenovelas on MyNetwork are Fashion House, starring the very plastic Bo Derek and the equally plastic Morgan Fairchild, and Desire, which each averaged a measly .7 rating in their first thirteen weeks on the air. New drama Wicked Wicked Games, starring Tatum O'Neal, and others have rated poorer than that since they debuted earlier this month.

Does anybody watch the telenovelas on MyNetwork? I hear the promos for them all the time on the radio and they sound so terrible... and not good terrible but just terrible terrible.

As we all get ready to welcome in the new CW network, it stands to reason that the merger must have left a few stations out there holding the bag. What is to become of them? The answer for some is that they will now be a part of News Corporation's myNetworkTV. The network begins airing its two original programs Tuesday, September 5th.

Those programs are Desire and Fashion House. Modeled after the popular telenovelas, each show will run five days a week, Monday through Friday, with a recap on Saturday. Rather than the endless run that normal American soap operas have, the myNetworkTV shows are each planned to run 65 episodes. As they come crashing to what promises to be a hectic conclusion after 13 weeks, two new shows will debut to run for the next 13.

Desire kicks off the night at 8PM. It is the story of brothers Louis and Alex Thomas. On the run from the mob, they make their way to Los Angeles. There, they both fall for the same woman and complications ensue as they deal with that and the mob gets ever closer. Desire is adapted from 2004's Mesa Para Tres (Table For Three).

Kelsey Grammer is returning to comedic television, but only behind-the-scenes. He has agreed to direct the CBS comedy pilot, My Ex-Life, about about two divorced couples and the way they deal with life after divorce. Former Love Monkey and Ed actor Tom Cavanah snagged a lead role in this show.

Despite a list of cancelled shows, The CW doesn't think that Wayne Brady is bad luck. The new network has picked up a comedy pilot called Flirt, starring Brady as the only man working at a women's magazine.

Bo Derek has joined the cast of Secret Obsessions, a telenovela-style, primetime soap opera on My Network TV, the network that FOX is creating out of its UPN stations that lost their affiliation earlier this year. Secret Obsessions is about the glamorous, yet ruthless world of fashion. Derek will play Maria Zianni, a mega-bitch who runs a fashion corporation.

Even when he played Aidan on Sex and the City, John Corbett has always been a little bit country. That's why he gave up acting in 2005, headed to Nashville, and grew out his chops. He spent the last year writing and composing songs for a country album with guitarist/friend Tara Novick. Now he has a self-titled album and a video, which you can see on AOL. The video is for a song called Good to Go, and it features your usual country stuff: hay bales, horses, tractors, and dirt. Oh yeah, and it also has a few cameos by Bo Derek, John's real-life girlfriend. You can hear samples of all the songs on his debut album over at his official website. Corbett isn't signed on with a record label because he didn't like their recommendation of waiting a year to create a "marketing strategy" for his album. It's his first album, but it's also a life-long dream for him, so he probably wanted to start the country music part of his life as soon as possible. Even if you don't like the style of music, you've got to admire the guy for walking away from it all to pursue his dream.
