Jamie Lynn Spears has a reputation as a bed-hopping, hard-drinker in her hometown, according to a new report.

A U.S. publication claims that Britney’s 16-year-old sister has often cheated on boyfriend Casey Aldridge, who is believed to be the father of her child.

A source from Jamie Lynn’s hometown of Kentwood, Louisiana tells Star: "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 percent."

Another friend tells the magazine that Jamie Lynn partied hard to forget her family troubles: "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."

The most shocking revellation comes from the source who claims that, days before announcing her pregnancy, the Zoey 101 star asked a boy for sex at a party with the line,  "It's cool, I'm pregnant. I can't get pregnant again!"

The Spears' are one classy family...
