Jenelle Evans' sister isn't happy about the news of her pregnancy.

After the Teen Mom 2 star confirmed she and boyfriend David Eason, whom she's been dating since last fall, were expecting a child with a post and photo on Instagram, Ashleigh spoke out on Facebook, revealing her disappointment in her announcement.

“It makes me sad for my poor nephew,” Ashleigh said of how Jenelle's pregnancy could eventually impact Jace, via Starcasm. “One day he’s gonna resent his mother and say wow!! Mommy only cares about hooking up with men and having different babies with different men while I’m being raised by…someone else.”

Following Jace's birth in 2009, Barbara Evans, Jenelle and Ashleigh's mom, was given custody of the child. Then, years later, after suffering a miscarriage while married to ex-husband Courtland Rogers, Jenelle became pregnant again and in June 2014, she welcomed her second son, Kaiser, now 2, with then-boyfriend Nathan Griffith.

“It’s sad, 3 babies all different dads before 25, no real job skills, no formal education, no life skills. I hope someday she realize that she’s done a lot of hurt,” Ashleigh concluded.

Jenelle announced her baby news earlier this weekend on Instagram. Along with a photo of her baby bump, Jenelle told fans she and Eason would be welcoming a baby girl in January of next year.
