    Casey Aldridge, the father of the baby that Jamie Lynn revealed in an interview with OK! Magazine Tuesday, is variously reported to be aged of 18 or 19.

    However, people wonder where the two young people were 12 weeks ago as she said she was 12 weeks along. 

    In Louisiana, where they both live, the age of consent is 17, and what obviously must have gone on between them might qualify as criminal carnal knowledge of a juvenile -- either a felony or misdemeanor, depending on just how old he is.

    In California, where she stays while the TV show "Zoey 101" is being shot, the age of consent is 18, and the relevant charge would be unlawful sexual intercourse, a misdemeanor.

    Jamie Lynn, the star of Nickelodeon's "Zoey 101," said she met the baby's father at church.
