Now, in an exclusive interview with E! News, another former protector of the pop tart has a strikingly different account of Spears' mommying prowess.
"In our time with Britney, we've never seen anything in a negative sense," Mark Chinapen, who worked for the pop star in 2007-08, tells E! News.
Chinapen says that he often saw Spears with her two sons, Sean Preston and Jayden James, and that he never saw anything as described in the lawsuit filed this week by former bodyguard Fernando Flores, who claimed to have seen Spears "savagely hit" one of her boys.
"If there was an issue, we would have said something to her or authorities when it came to the kids," says Chinapen, CEO of Big Time Affairs, who has also provided security for Carmen Electra and Lindsay Lohan. "But we never saw anything negative."
Chinapen says that during his tenure the L.A. County Department of Children and Family Services conducted an investigation into alleged abuse, "but at the end of the day, there was no issue. They came, were happy with the results, and walked away."
Chinapen says that his time with Spears was relatively calm—nothing like the erratic, harassing behavoir Flores accused the singer of.
"It was very normal. Starbucks runs, going for lunch, driving, shopping, buying clothes, and going out to events. That's it," Chinapen says.
"Britney is one of those people that likes to conduct her own business and go around and do her thing around town. She's not looking for someone to be in her face 24/7, just someone to assist when they're needed."
Adds Chinapen of life as a celebrity bodyguard, "You're taking care of someone, protecting them from the outsiders, whether it be the paparazzi or a fan that is getting too close, and that's it. There's nothing bigger than that."
