Poor Joseph Duggar [VIDEO] and Kendra Caldwell--their wedding prompts more speculation about Duggar family members than the happy couple themselves. Case in point is Jana Duggar. Does it look to you like the "19 Kids and Counting" daughter had big weight loss recently? "Counting On" episodes and Instagram show her steadily shrinking. And that seems to suggest a new romance for the Reality TV star.

Jana Duggar rocks sexy

Only reality television fans who live under a rock can fail to notice that "Counting On [VIDEO]" ain't your granny's "19 Kids and Counting." It's farewell regulation homeschooling jean maxis, hello curve-hugging skirts and blouses for the celebrities.

Not that Jana was ever chubby. But in her slinky dress and heels, she looked sexy and svelte at Joe Duggar's wedding. Her face is so tanned and toned she appeared to have had plastic surgery or Botox.

The celebrity sister may have (don't tell Kendra) outshone the bride.

Jana: from hot to hotter

In the lineup of Duggar girls, Jana just might trump Jessa Duggar Seewald for prettiest (there was a Facebook vote, not author opinion). It's a close race with Jinger Duggar Vuolo and her wicked "transgender" pants-wearing. None of the "19 Kids and Counting" ladies are slouches and Michelle Duggar encourages 'em to paint and curl it up. Jim Bob Duggar is "Counting On" 100+ grandbabies so the girls embellish assets, wed and bed young.

Jana Duggar's all dressed up with nowhere to go?

There's the $64,000 Duggar Family question: why is the gorgeous eldest girl still single? Is she just the token nanny? The reality television star was left out of a "Counting On" episode where Jessa and Ben Seewald visited Jinger and Jeremy Vuolo.

At the wedding, married siblings Jill Duggar Dillard and her husband Derick Dillard, Jessa, Jinger and Joy-Anna and Austin Forsyth were pictured together. Jana was shown with the younger "19 Kids and Counting."

Michelle Duggar grooming Jana for love?

So obesity's no problem for the family, though an eating disorder like anorexia may be. The "19 Kids and Counting" mom famously tells women to lose weight if they're "Counting On" attracting a man. She even hinted as much to Anna Duggar when Josh Duggar and the incest, adultery and pedophilia scandal broke. When one of the girls is in a relationship you can usually tell by weight loss. In fact, Joy-Anna Duggar Forsyth lost so much weight when courting that she looks bigger now than her 3-month pregnancy. Is Jana preparing for a big announcement of marriage?
