The States of California and Louisiana should revoke all licenses issued to people named Spears immediately. This is definitely a DNA thing.

The mother of pop star Britney Spears ran over a bike-riding youngster with her car and killed him in 1975, the National Enquirer reports.

"To this day, Lynne hasn't gotten over what she did. She gets that terrified look in her eye when she is thinking about it," said a source close to the Spears family, noting that the boy died at the age of 12.

"She has told only a few people about the accident and always says, 'Please don't think I'm a bad person.'"

Lynne Spears was just 20 when the tragedy occurred in her hometown of Kentwood, La., the same year she married Jamie Spears (above).

When the accident happened, Britney and Jamie Lynn Spears' mother was driving her brother to the hospital after he'd suffered an injury.

"It bothers Lynne still to this day," said a rep for Lynne Spears. "She has told only a few people about the accident and always says, 'Please don't think I'm a bad person.' She really doesn't like to talk about it."

Hey, at least Britney Spears hasn't killed anyone - though as we showed you earlier today, it's definitely a good thing K-Fed got custody.
