TMZ said the teen confirmed in an OK! magazine article -- in the issue set to hit stands Wednesday -- that she is expecting boyfriend Casey Aldridge's baby.

Jamie Lynn and her mother were both interviewed for the six-page piece.

The star of Nickelodeon's "Zoey 101" said she first met Aldridge at church.

Sources told TMZ Jamie Lynn has not shared the news with her big sister, who currently is embroiled in a nasty custody battle with her ex-husband over their two small children.

"We respect Jamie Lynn's decision to take responsibility in this sensitive and personal situation," Nickelodeon said in statement. "We know this is a very difficult time for her and her family, and our primary concern right now is for Jamie Lynn's well being."
