What does savvy mean to Forbes? Oh, just multimillion dollar deals with stakes in big-name companies, self-named and designed clothing lines, and fragrances named after yourself with all advertising starring, of course, you.

Bottom line, these celebs are maxing out their potential by taking advantage of lucrative business deals. I know you've all seen Jennifer Aniston's SmartWater ads; the company is definitely capitalizing on her ability to appeal to guys and girls. She supposedly came out of this deal with about $10 million.

Other stars on the list include women you might have guessed. You know, the ones who don't even need last names? Madonna continues to top herself year after year, and 2007 was no different. Her biggest deal this year was the $120 million she got when she signed on with Live Nation. Then there are the models who've shown us the brains behind their beauty — the business tactics and projects of Tyra, Gisele, and Heidi that all made headlines this year.
