thought"American Idol" winner Kelly Clarkson appeared on the cover of Redbook recently and it prompted comments about her weight gain after yo-yo weight loss. That's predictable, says the singer: folks are always body-shaming celebrities. But the joke's on them, says the mom of two, because she's happier fat than skinny. And be prepared for a shock: Clarkson claims excellent sexual relations thanks in part to "obesity."

Kelly Clarkson is "fat and happy"

In discussions of body size, it's taboo to use the f-word. But Kelly Clarkson doesn't pussyfoot around being P.C.

She bluntly says that it's when she's fat she's happiest. Whenever the "Love So Soft" singer appears overweight, people worry that there's something wrong and that's why she's packing on pounds. But no, assures the 35-year-old, weight gain "represents happiness in my emotional world. For me, when I’m skinny is usually when I’m not doing well.”

Kelly Clarkson and Miranda Lambert talk body-shaming

In the Redbook interview, Clarkson says her country music co-star Miranda Lambert experiences similar fat-shaming. Lambert's ex Blake Shelton is currently in the limelight on "The Voice", as a super couple with Gwen Stefani and now winning People magazine's "Sexiest Man Alive." Both Lambert and Shelton lost a great deal of weight around the divorce.

It had folks scrutinizing what went wrong and blaming what happened before the divorce on weight gain and blaming the weight loss on the divorce.

Celebrities weight loss issues

Maybe it isn't body-shaming, but the public is morbidly fascinated with Celebrities' weight. They're eager to learn why this one gained weight or how that one lost it.

There's such a hyper-focus that anorexia and eating disorder behavior plague high-profile people. Even the new crop of reality TV celebs face it. Mama June made a living off obesity in "Toddlers & Tiaras" and "Here Comes Honey Boo Boo." Now folks are eating up June Shannon's celebrity diet tips on reality television's "From Not to Hot." But Clarkson is sharing health tips of another kind.

Happy body image, sexually healthy

You might think that skinny people are happier and have a better sex life. While it's true that complication from obesity, like type 2 diabetes, high blood pressure, heart disease, and erectile dysfunction impair sexual health, so does thin obsession. Clarkson boasts an active, vigorous sex life with husband Brandon Blackstock, thanks partly to a healthy and positive body image. It also reflects a growing trend in celebrity thought, to embrace bigger bodies.
