Britney Spears came under fire this week after she was photographed driving her SUV with her infant son perched on her lap without a seat belt.

“I made a mistake and so it is what it is, I guess,” Spears tells “Access Hollywood” in an interview that was to air Thursday. But the 24-year-old pop star blamed the paparazzi who took the pictures Monday, saying she was trying to escape their harassment in what she called a “horrifying, frightful encounter.”
