How did she do that?! Not only is Teen Mom 2’s Jenelle Evans embracing second-time motherhood, but she’s also happily showing off her body just two months after giving birth to son Kaiser.

The former wild child, 22, made a trip to New York City with boyfriend and baby daddy Nathan Griffith to tape a reunion special of the popular MTV series, and showed off her trim figure in the process.

Posing in her hotel room wearing a black, low-cut crop top and fitted floral skirt, Evans looked slim and fit.

“Feeling quite sexy,” she tweeted on Aug. 23 with one selfie.

The reality star happily snapped pictures with her boyfriend of more than a year before heading the show’s taping. The couple welcomed baby Kaiser in late June, and have been inseparable ever since.
