In case you missed it, Serena Williams asserted her dominance in women's tennis once again by winning the French Open on Saturday. If you wondering why we say "assert her dominance," well, Serena has now won the 2012 Wimbledon, 2012 US Open, 2012 WTA Championship, a gold medal in the 2012 Summer Olympics and this past weekend's French Open.
As a fellow 31-year-old dominating her field, Beyoncé took the time to congratulate Serena with a hand-written letter, as well as adding a little personal message at the end. Check it out in the thumbnail.
