The 21-year-old Teen Mom star tweeted early Thursday morning, "Baby bumpppp. My little angel," alongside a link to a photo she had posted on instagram of herself posing in front of her bathroom mirror in nothing but a bra and sweatpants.
Earlier this week, Evans' new husband Courtland Rogers told Star magazine recently that they're expecting a child together, sharing that Evans is over six weeks pregnant and the baby is due on September 4.
Evans confirmed just how far along she is in her pregnancy via Twitter.
"I'm 7 weeks not 4 lol," she tweeted a follower, who was skeptical her belly would be showing at only four weeks pregnant.
Evans -- who has been known for struggling with drug and legal issues in her recent past -- is already a mom to her son Jace Evans, who is, however, in the custody of the reality TV star's mother Barbara Evans.
"My mother and I had the best conversation yesterday about getting Jace back in the future. Everything is looking up for me!" Evans tweeted today, adding that she's been "clean for 2 months."
Rogers also has a daughter named JaJa from a previous relationship. He, like Jenelle, does not have custody of his first-born and is apparently looking forward to starting over.
Jenelle and Rogers wed in a quickie ceremony in early December and their relationship has seemingly been on the rocks ever since.
Jenelle started dating Rogers in September and revealed in late November they had gotten engaged only months after she had called off her engagement to ex-fiance Gary Head this past summer. The reality TV star and Head had announced their engagement in May after dating for five months.
