Carol Vorderman

Carol is best-known for being Richard Whitely's assistant on Countdown, but went on to outshine her co-presenter. The Leeds-born celeb has become something of a national institution, with innumerable TV appearances and a regular newspaper column. Several high-profile style changes have given the mother-of-two an increasingly glamorous image as her success has grown. And with an IQ of 167, she is obviously a great deal more than just a pretty face.
