Looks like having a potty mouth won't hurt you too much. Serena Williams is one of 11 outstanding ladies Glamour magazine has chosen for its Women of the Year issue.

Glamour cites Williams's competitive spirit and drive as a testament to her success, even in the face of hardships like the tragic murder of her sister Yetunde and her rise through the rankings after suffering injuries in 2006. This year it all came full circle for Williams when she captured the Wimbledon victory against her sister, Venus — whom she credits as being a major force in motivating her to work the hardest and become the best.

Besides her Wimbledon victory, Williams has 11 Grand Slam titles, two Olympic gold medals, and has earned more prize money than any female athlete in history. But her trophies and bank account aren't the only reason Glamour thinks Williams is tops. Between winning matches, she's managed to start her own clothing line, pen an autobiography, and open a school in Kenya through her Serena Williams Foundation.

Who else did Glamour name as Women of the Year? Some of the other notables Williams holds court with are Michelle Obama, Maria Shriver, Rihanna, and poet Maya Angelou.
