Jamie Lynn 'has hard-partying lifestyle'

Jamie Lynn Spears has earned a reputation for sleeping around and partying in her hometown, say reports.

The 16-year-old drinks heavily and regularly cheats on her boyfriend Casey Aldridge, according to America's Star magazine.

A source commented: "I know for a fact that Casey was not the first guy she slept with - or the last. There were at least two others. I know that 110%."

Another friend added: "Some people drink to have a good time. But she drank to get wrecked. She drank to get messed up and forget about her mother, her sister and all of that."

Jamie Lynn allegedly asked a boy for sex at a party, despite recently becoming pregnant with Aldridge's child.

She reportedly said: "It's cool, I'm pregnant. I can't get pregnant again!"

The Zoey 101 star announced she was expecting a child in December last year.
