Odus Jackson, uncle to Casey Aldridge, said Aldridge and Jamie Lynn Spears have no plans to wed yet.
"They may or may not [get married]," he said. "You just never know."
Jackson, a pastor in Gloster, Miss., said he hopes the two marry, but he is realistic.
"I hope they will stick it out and get married for the child's sake and their sake," he says. "But if they're not in love and it was just a fantasy, they don't need to make the same mistake twice."
