Don't mess with her man!

Teen Mom 2’s Jenelle Evans wasted no time clapping back at an online troll who asked if her fiancé, David Eason — who suffers from vitiligo — had AIDS.

The heated social media exchange took place on Monday, June 26, after the 16 and Pregnant alum, 25, posted a sweet snap of David taking a nap with their five-month-old daughter, Ensley, on Instagram. "#DadMode gets ya tired sometimes,” Jenelle innocently captioned the photo.

In the pic, David’s skin condition can be seen on his left hand. Not long after the post went up, one of Jenelle’s followers shared this insensitive comment: "Does he have aids whats up with his hand?”

Naturally, this rude remark infuriated Jenelle and she immediately defended her man, writing, "It's called vitiligo you f–king idiot. It's a loss of pigment in your skin. People are models these days for it. You need to research STDs if you don't know wtf AIDS does to you…. and def don't do that s–t to your skin like that. Maybe you're the one with AIDS and don't even know cuz your [sic] as dumb as a box of rocks my friend.”

While David has never publicly addressed his vitiligo, he has never shown any sign of insecurity on Teen Mom 2 or in any of his social media posts.

The North Carolina-based couple announced their engagement back in February, just weeks after welcoming Ensley. "We decided on forever! #PerfectTiming," Jenelle — who is also mom of seven-year-old son Jace, whose father is Andrew Lewis, and two-year-old son Kaiser, whom she shares with ex-fiancé Nathan Griffith — wrote at the time.
