The 21 year old's new husband, Courtland Rogers, reveals Evans had no idea she was expecting when the couple wed in a North Carolina courthouse on 4 December (12), but they couldn't be more delighted with the unexpected news.
He tells Star magazine, ""Me and Jenelle are so happy that she's pregnant. She told me, 'I'm looking forward to a second chance.'""
Evans' due date is 4 September (13).
The young reality TV regular is already a mother to three-year-old son Jace, but her mum Barbara has custody of the boy.
Rogers also has one-year-old daughter, called Jordan, from a previous relationship. He does not have legal custody of the child.
