Serena lost her match against Kim Clijsters at this years U.S. open. Serena lost her cool which ultimately made her lose the match up. Seems what happended is the linesmen called the wrong penalty and Serena checked her on it, along with other choice words. This clip is edited well, but I seen one with the curse words edited. I felt kind of bad for Serena. I know how it is to have a hot head. Sometimes I have to check myself. Serena accepted the lost packed her things and went behind the scenes.
