NEW YORK - Lynne Spears say she's responsible for her daughter Britney's troubles. "I blame myself," she tells Life & Style Weekly magazine. "What mother wouldn't?" "I wish I'd been there more while she was touring," Spears says. "But I couldn't be. I had the other kids to look after."

Spears, the mother of three children with ex-husband Jamie Spears, is writing a memoir about raising her family in the public eye. "Pop Culture Mom: A Real Story of Fame and Family in a Tabloid World" is set for release May 11, which is Mother's Day.

"I didn't raise my children to have Hollywood careers. This all just exploded in my face, and big dreams became big headaches," says Spears, who recently reconciled with her 25-year-old pop singer-daughter after a period of estrangement.

Britney Spears, a tabloid fixture thanks to her public blunders and turbulent personal life, was ordered last month to temporarily surrender custody of her sons, Sean Preston, 2, and Jayden James, 1, to ex-husband Kevin Federline.

"Here are two parents who care about their kids," Spears says. "They're good people. With my daughter's, Kevin's and the boys' interest at heart, I'm trying my best to bring them together, to bridge the gap. I think things are getting good."

"Britney loves her kids from the pit of her soul," she says.
