Lisa Rinna says of the nude Playboy pictures, “I’m 45 years old. I look good right now. Why not? Why not celebrate the beauty of the female body?”

Eva Longoria Parker, star of Desperate Housewives, says of the top spot, “I think the timing for this is pretty funny, actually, but also really great.”

Longoria Parker is talking about how her character, Gabrielle Solis, was “put through the wringer this season and survived. I love that Gaby has been able to withstand time—along with the bad haircuts and all the extra pounds—and is still considered sexy.”

Simon Baker was named TV’s sexiest male star.

Check out the Tina Fey/Alec Baldwin TV Guide cover picture above, and inside the issue, Tina Fey dishes about Sarah Palin, her new book and stand-up comedy.

Tina Fey on Sarah Palin: “When I first saw her, I didn’t think we looked alike at all. Then during the convention, I started to think, ‘OK, maybe a little.’ I expected people to be like, ‘Ahhh, we thought it’d be better than that.’ I stand by the pieces as both fair and quite gentle…We glue my ears down. That’s one of the tricks… I’ll tell you, that lady is five times better-looking than I am. She’s 44? She’s got none of that droopy s—. She’s keeping it tight!”

Fey on her new book deal: “I wouldn’t write a big tell-all, behind-the-scenes thing…it would be humorous. Unfortunately, I could become the Erma Bombeck of the 25th century, because it’s going to take me a long time to write.”

For instance, Mario Lopez shares his need to sweat, saying, “I never feel awake unless I’m sweating.” Yuck.

And Audrina Patridge shares this fitness tip with TV Guide readers: “I wear heels when I vacuum because it works my calves and my butt.” Uh-huh.

“Desperate Houswife” Eva Longoria is this week’s TV Guide covergirl.

The TV Guide Channel has replaced veteran red carpet fashionistas Joan & Melissa Rivers with Lisa Rinna.

The former “Dancing With the Stars” finalist has signed a multi-year contract with the network. Lisa will host five red carpet pre-shows and five fashion recap shows, beginning with the Emmy Awards in September, as part of the deal.

TV Guide says they chose L.R because, “In addition to being an established TV star, she also has fashion expertise as both a business person and commentator, so she is a great fit for this role and for our brand.” She owns two L.A. area boutiques called Belle Gray.

The network released a statement saying, “TV Guide Channel is very appreciative of Joan and Melissa Rivers’ contributions to the success of our Red Carpet programming over the past three years. We wish them the best in their future endeavors.”

Joan Rivers says: “I will tell you my true feelings and experiences, as soon as we finalize our new deal.”

Joan, who invented red carpet fashion reporting, and daughter Melissa had been with TV Guide since January 2005, after leaving E!
