If you're a sports fan, or even if you're not, this has been the year of Serena Williams. In addition to setting the new record for number of Open-era grand slam titles (23) and being the highest-paid female athlete ($27 million over the past 12 months from June), the tennis pro has flexed her muscles on and off the clay court (and done it while pregnant to boot).
