Jamie Lynn Spear’s baby joy turns to tears because her wedding to Casey Aldridge is off!

In the new issue of Star, on newsstands now, we break the exclusive news that the pregnant teenager has called off her wedding.

Ever since the Zoey 101 made the shocking announcement that she’s pregnant, her mom, Lynne Spears, has been pushing her to marry baby daddy Casey.

And while it seems like the teen mom-to-be has been trying her best to do the right thing, insiders tell Star that the tension between the two young parents-to-be has become so intense that it’s doubtful they will ever tie the knot.

“Jamie Lynn and Casey have been fighting non-stop about everything, from what to name the baby to what to eat for dinner,” a source tells Star. “And now she’s called off their wedding plans.”

Despite reports that the couple bought a house near Jamie Lynn’s hometown of Kentwood, La,. Star has learned that 17-year-old Jamie Lynn has moved back into Serenity, the Spears’ family estate — and her dad, Jamie Spears, has flown from sister Britney’s side in L.A. to be there for his younger daughter.

“Jamie Lynn, Jamie and her mom are all staying at Serenity right now,” a second insider reveals. “They’ve been busy decorating the baby nursery.”

Casey, 19, is “in and out,” the second insider says. But despite the couple’s frequent trips to Wal-Mart, their relationship is seriously strained — and it’s been the talk of the town.
