The ENQUIRER exclusively reveals Britney Spears‘ mom Lynne is hiding a shocking secret tragedy

The mother of the pop star ran over a bike-riding young boy with her car and killed him!

The accident occurred in 1975, and Lynne Spears is still haunted by the death of the 12-year-old boy.

"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.

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

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

When the accident happened, Britney’s mom was driving her brother to the hospital after he’d suffered an injury.

"It bothers Lynne still to this day," said a representative for Lynne Spears.

"She really doesn’t like to talk about it. She just wanted to forget that it ever happened – but she can’t."
