Jamie Lynn Spears is reportedly ready to go it alone when it comes to taking on the challenge of teen motherhood.

Insiders say that boyfriend and baby daddy Casey Aldridge has been largely absent since the birth of their daughter Maddie on June 19.

Whilst Casey has been staying at the couple's Kentwood property 'Liberty,' Britney Spears' 16-year-old sister has apparently been holed up in 'Serenity', her family's estate.

"Jamie Lynn is with the baby day and night and refuses to let anyone hold her, and that includes her mom," a source tells Star.

"When Casey comes around, Jamie Lynn tells him to leave."

It's claimed that the only person actively trying to ensure that Casey plays a role in his baby daughter's life is his mother Joyce.

"She calls Serenity every day, and it annoys Jamie Lynn to no end," adds the source.  

"If Joyce has her way, Casey would be forced to spend more time with the baby, even though he seems uninterested in fatherhood."
