LATEST: JAMIE-LYNN SPEARS is planning to marry the father of her unborn child CASEY ALDRIDGE, his pastor uncle reveals.

Britney's TV star sister shocked the world when she announced this week (beg17Dec07) she is pregnant at the age of 16, with 18-year-old Aldridge's child.

Subsequent reports have suggested the pair are set to split - but Adridge's uncle, Reverend Odus Jackson claims they are smitten and have discussed marriage.

Jackson tells the New York Post, "Jamie Lynn and Casey want to get married. I know Casey does, and he says she does too. "I know what he has expressed. Casey wants to get married and do it as soon as possible."
