Spears blames the paparazzi for her car seat-rule violation

Britney Spears has taken responsibility — well, some of it — for driving with her baby son, Sean Preston, sitting in her lap.

"I made a mistake and so it is what it is, I guess," Spears tells "Access Hollywood" in an interview that aired Thursday.

Several photos published Tuesday showed Spears driving her sport utility vehicle in Malibu, Calif., with her 4-month-old son perched on her lap rather than strapped into a car seat in the back seat.

The 24-year-old pop star said she did it because of a "horrifying, frightful encounter with the paparazzi."
