Condoleezza Rice
Condoleezza Rice is a political scientist who served as the 66th US Secretary of State from 2005 to 2009. She was also the National Security Advisor to President Bush, making her the first woman to hold the position in the country.
Just like other successful and strong-willed women, Rice seems to prefer the single life. She was engaged for a brief period to Denver Broncos NFL player, Rick Upchurch, but they didn’t end up at the altar as planned.
