Only six months after giving birth, 'Teen Mom 2' star Jenelle Evans has stolen the show with her fantastic physique while on a fancy beach vacation.

The Teen Mom 2 star spent most of her New Year relaxing in the tropics in St. Thomas. While she was on the trip, Jenelle got engaged to her boyfriend, Nathan Griffin, and spent the rest of her relaxing time just exploring the island, lounging on the beach, and other tourist-y things.

But the 23-year-old reality TV celebrity really made a splash when she posted photos of herself and her tropical surroundings on Instagram. Fans not only got excited about the scenes of warm sand and cool waters, but because the celebrity looks surprisingly fit.

Evans gave birth to her second son, Kaiser, in late June, only six months ago. For most mothers, the year following one's pregnancy means lots of flowy clothing, lots of baby clothing, and a lot of stredd. But since when has Evans backed down from a challenge?

"I can't get over this view!" the Teen Mom 2 celebrity captioned with a photo of herself. An incredible ocean view showed in the background. On January 11^th, Jenelle posted two more pictures, one with her new fiancé. The caption read, "Last day for Magen's Bay lol," and the picture showed of her beach tan and some abdomen tattoos.

Now that her holiday break is over, Jenelle is ready to go back to her children. "I can't wait to see my baby Kai! that's all I keep thinking about right now."
