So True? So False? Is Jessica Simpson Really Going on The Biggest Loser?!

There's a story that the pregnant pop star is going to appear on the hit NBC show. For reals?!

Jessica Simpson looks lovely—she's got a baby on the way and she's the picture of full-belly health.

We also imagine that the pop star turned fashion mogul is enjoying the brief respite from all the scrutiny regarding her weight that she seemed to face on a daily basis before she got pregnant.

And while a report that she had already signed up to be a Weight Watchers spokeswoman after the baby is born proved bogus, surely Simpson is thinking somewhat about how she's going to get back into red-carpet shape after her nine months are up.

But appearing on The Biggest Loser, as we heard today? That sounds a little far-fetched, doesn't it? Well, hang onto your spandex, fans, because this story is...

So true—but not as a contestant, of course.

NBC has confirmed that a still-pregnant Simpson will be on the March 13 episode of The Biggest Loser to treat two challenge winners to a tour of her showroom and free goodies from her clothing, handbag and skincare lines. (NBC and E! are both part of the NBCUniversal family.)

"I was so happy when I was asked to help style two contestants from The Biggest Loser," Simpson said. "I am truly inspired by how hard these contestants worked to accomplish their goals for a healthy lifestyle. It was so much fun seeing them try on clothes they would have never fit into before and feeling sexy. We had an amazing day together!" 

And don't think for a second that Simpson's appearance on the show isn't a carefully styled event in and of itself.

NBC's new competition show, Fashion Star—featuring Simpson, Nicole Richie and designer John Varvatos as contestant mentors—premieres March 13, right after The Biggest Loser.
