Sassy. Splendid. Stunning. These are just a few words to describe how we feel about the hot celeb hairstyles we spotted this week. Serena Williams accepted her fifth Wimbledon title (go 'head girl!) in a head full of ravishing curls while gospel great Kim Burrell attended the ESSENCE Music Festival in sleek, soul-stirring strands. Take a look at all this hair fabulousness for yourself!
