Cover Girl makeup model Niki Taylor, 26, is listed in critical condition in an Atlanta hospital after suffering severe internal injuries as a result of an automobile accident that took place early Sunday, her agent informed Reuters on Tuesday. The supermodel, who is the single mother of 5-year-old twin boys, was a passenger in a car that crashed, said Lou Taylor of TriStar Management agency. In a brief statement, he said that the driver, who was not identified, lost control of the car and struck a pole. No other vehicles were involved. Taylor, a Florida native, has been modeling since she was 13. Her younger sister, Kristen Taylor, was a promising model until she died from asthma at the age of 17 in 1995.
