Celebrities have long dabbled in design, but with the growth of TV shows and websites that follow everything celebrities say, wear and do, interest in their clothing lines has risen in recent years. North America revenue from celebrity clothing lines, excluding merchandise linked to athletes, rose 6 percent last year to an historic peak of $7.58 billion in 2011, according to the latest figures available by The Licensing Letter, an industry trade. That's on top of a nearly 5 percent increase in 2010. (AP Photo/Mark Lennihan)
