Superstar Madonna has come under fire for failing to properly restrain her 17-month-old child in her vehicle. Much like the controversy surrounding pop star Britney Spears last year, Madonna's adopted son David is at the center of media attention after he was recently photographed not strapped into a car seat. The 48-year-old and husband Guy Ritchie loaded their three children into their Escalade SUV after March 2 services at the Kabbalah Center in Los Angeles, but baby David was not properly restrained. A witness tells Us Weekly , "There was no car seat. (Madonna) sat in the middle row, and they left with David on her lap." The following day, Madonna allegedly defied the law once again by sitting in the middle of the vehicle with 6-year-old son Rocco not properly secured. A representative for the singer slams the claims, saying, "Proper security measures are always taken for Madonna's children."
