Madonna was forced to phone for police help after two cars allegedly tried to ram her off the road on New York City's Fifth Avenue. Thursday's street scare saw the singer's driver call cops over fears their pursuers had evil designs on the star. A source tells British newspaper the Daily Star, "Madonna's driver noticed there were two big vehicles driving closely behind her and tried to ditch them by turning onto Fifth Avenue.He was particularly concerned as Madonna has recently been sent some disturbing mail - which has been somewhat threatening to say the least. But as he turned to go along Fifth Avenue, the two following cars tried to ram Madonna's car off the road and she was forced to dial 911. Eventually, after a high-speed chase, her driver managed to lose them and they reported it to the police in a lengthy phone call. Madonna is carrying on as normal but she's stepped up security."
