Rumors are surfacing that Casey Aldridge may not be the real father of Jamie Lynn Spears baby-to-be, and that Aldridge is being paid off to accept responsibility for the "boo-boo".

It has been alleged the 16-year-old actress - who announced she is expecting her first child with long-term boyfriend Casey earlier this month - was having an affair with an older man on the set of her Nickelodeon TV show "Zoey 101".

The Spears family are allegedly desperate to keep the man's identity a secret, and have paid Casey to pretend to be the father instead.

A source told America's Star magazine, "Casey is being paid off to be the family's fall guy while the real father remains unidentified. The man many suspect is the father, however, would face rape charges and probably prison time if he were to come forward and admit he had sex with Jamie Lynn."

A family insider added, "Some of us have doubts as to the legitimacy of the claim that Casey is the father. Before the news of the pregnancy, how often did you see them together? Jamie Lynn has dated Casey on-and-off over the past two years. But it was not steady. Jamie Lynn went through a time of partying, and Casey was just a part of that."

EL, of crazydaysandnights.net, surmises that the real father is someone who is old enough to be Spears' GRANDfather, and is an exec at Nickelodeon.
