Just how much money does Steven Tyler need? Evidently all that touring with Aerosmith and starring on "American Idol" isn't giving him enough scratch. So now the Rock & Roll Hall Of Famer will be judging the second annual Great Lengths USA Challenge — a hair extension contest — in early December. No word on Mr. Tyler's fee, but the Grand Prize is $10,000 and a trip to Chicago to attend the 12th Annual Behind The Chair Stylist Choice Awards.
