Jamie Lynn Spears isn’t letting a little thing like pregnancy stop her from following in her trashy big sister’s footsteps.

Life & Style magazine is reporting that the 16 year old is refusing to give up her wild ways and is continuing to drink, smoke and stay out late, despite being just 4 months from giving birth.

The ‘Zoey 101’ star is causing a few sleepless night for her distressed parents, who already must be wondering where they went wrong with older sibling/troublemaker, Britney.

She has also prompted medical staff to point out the dangers of stress during pregnancy, which could be brought on by career concerns, teenage insecurities and questions regarding who the devil spawn’s father actually is.

Casey Aldridge is still considered the most likely candidate, just ahead of Eddie Murphy, Rod Stewart and K-Fed’s little brother.
