Teen Mom 2 star Jenelle Evans confirmed to MTV that she is going to be a mother again.

Evans is expecteing a child with her boyfriend of six months, Nathan Griffith. She is still in her first trimester but has not confirmed exactly how far along she is in her pregnancy.

Evans told the network she is "exhausted" and has been having constant morning sickness, but that that she and Griffith are extremely happy to be starting a family together. Though this will be their first child together, both are already parents to children in other people's custody. 

"We just want a child of our own that we can raise together as a family, and we want a stable relationship for Jace and [Griffith's] daughter [Emery]. We just want to settle down," she said.

Evans' 4-year-old son is in the custody of her mother Barbara, while Griffith's 2-year-old daughter is cared for by his ex-wife's parents.

Evans, who has been sober since 2012 after battling a heroin addiction, said the condition of this pregnancy is much healthier than when she was pregnant with Jace. She explained that her life is in a very different place these days.

"I think it would scare me more if I was in the situation I was when I had Jace," she said. "Now I'm in a stable relationship and I have my own place, my own car, a job...I can pay my bills. I'm just happy with my life right now."

MTV has extended filming for the fifth season so news of Evans' pregnancy can be taped and aired on the show, according to The Ashley's Reality Roundup,  

Evans is excited about her critics seeing the improvements she has made since season 4.

"I've got my life together now, and I'm a different person from what they've seen," she said. "I just can't wait for them to see how much I've bettered my life. I understand if they judge me now, but they won't judge me soon."
