Jenelle Evans Post-Baby Body: 'Teen Mom 2' Star Wears Tube Top

Jenelle Evans' body is back to its pre-baby size less than two months after she welcomed her second son.

Although Kaiser Griffith hasn't yet celebrated his two-month birthday, the Teen Mom 2 star appears to be back to size -- and isn't hesitating to show off her impressive weight loss. In fact, she is doing just that.

On Aug. 21, Evans shared a photo with fans on Facebook, along with the caption, "Had fun with my love last night. Went out for [Nathan Griffith]'s brothers birthday." In the photo, Evans is seen wearing a black skirt and red tube top. Standing beside her is Griffith, who looks to be loving her post-baby physique.

On June 30, Evans and her boyfriend of one year welcomed their first child together, son Kaiser (each party also has a child from a previous relationship). News of Evans' pregnancy hit the web late last year and was confirmed by the MTV star in Dec. 2013. At the time, Evans told MTV she and Griffith were thrilled to be starting a family and completely ready for everything it would entail. She also insisted her drug use and partying was behind her.
