Jamie Lynn & Casey: "Committed to Each Other"

Forget all the rumors you've heard regarding the relationship between young parents-to-be Jamie Lynn Spears and Casey Aldridge. He hasn't run off; they haven't broken up; no one's hiding from anyone. In fact, those closest to the couple reveal to OK! that the Zoey 101 star's 18-year-old beau has marriage on his mind!

"They are fully committed to each other," Casey's great-uncle, Pastor Odus Jackson of Galilee Baptist Church, tells OK!. "That’s how love goes. Jamie Lynn can have anyone she wants, and Casey is very popular too. But they keep on finding each other, and that makes me hopeful for their future. He wants to propose to her and get married!”

Since news of the 16-year-old actress' unexpected pregnancy broke in late December, friends say the couple have been basically inseparable. “Jamie technically still lives with her mama," one source explains, "but she spends her free time with Casey." Which means the two lovebirds are constantly making the hour-long trek between her home in Kentwood, La., and his place in Gloster, Miss., where Casey is busy working hard to earn a living.
