Jenelle Evans certainly knows how to attract attention. The "Teen Mom 2" star posted a topless selfie boasting weight loss just 13 days after giving birth to daughter Ensley Jolie. The half-naked selfie proved that the reality television star won't take fat-shaming lying down. Jenelle's ex (Nathan Griffith) had body-shamed the mom of three. And in "Revenge Body" fashion, Evans fought back.

Jenelle Evans' nude selfie wows

The Instagram selife shows that just "2 weeks postpartum" (as the caption reads), the reality show mom has a tiny tummy and amazingly toned body.

Her weight loss is almost as noticable as co-star Leah Messer. What's Evans' secret to losing pregnancy weight so quickly? Three kids keep her busy, but not too busy for staged photoshoots. The "Teen Mom 2" star posed with Ensley in a milk bath. As in the recent Beyonce pregnancy pic, Jenelle wore a lace bra and flower crown. Pictures of baby daddy David Eason cuddling his daughter looked more natural.

Jenelle Evans works it out

After Nathan Griffith made cracks about her weight, the "Teen Mom" decided to shed some pounds and tone up. Her hardcore fitness workouts resemble "Revenge Body" with Khloe Kardashian. Evans keeps up with the "KUWTK" star on selfies, too. Like her fellow reality TV celebs, workouts are shared on Twitter and Instagram.

Folks have wondered how much is exercising and how much is posing, and also, how much is plastic surgery. Jenelle's co-star Kailyn Lowry underwent plastic surgery and a tummy tuck but still struggles with weight.

Jenelle Evans fights her butt off

You've heard of Chef Rocco DiSpirito and "Cook Your Butt Off"?

The "Teen Mom 2" star fights the pounds off. She's in not one but two custody battles over her older children. Jenelle is quarreling with her mother Barbara over eldest son, 7-year-old Jace. For the recent birth of Evans' daughter, Evans' mom and Eason clashed in the delivery room. Mom says Eason threw her out, but Jenelle says Barbara just wants pity, and stormed out herself.

The reality TV mom may even be more combative than "Teen Mom OG" toughie Amber Portwood. On Evans' nude selfie, one commenter said this is why she's "trashy" and Chelsea Houska is "classy." At least it's not naked like Farrah Abraham with her porn star career.
