From The Chicago Tribune : Britney Spears has taken responsibility--well, sort of--for driving with her baby, 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. Spears has said she needed to escape a "horrifying, frightful encounter with the paparazzi." X17, the agency that snapped the pictures, said they were taken "in a very peaceful context." Spears disagrees. "Being put in the situation that I was in, it was kind of bad with the paparazzi," she tells "Access." "Last week, my mom and I went out and they were on us really bad, so you instinctively do what you need to do." The Los Angeles County Sheriff's Department said it won't pursue any charges.
