During her upset loss to Australian Sam Stosur, tennis legend Serena Williams lost her cool for the second time in three years at the U.S. Open.

Williams was looking to earn her 28th Grand Slam championship (14th singles) and fourth U.S. Open Women's Singles title, but fell to the upstart Stosur 6-2, 6-3. During the match, Williams was docked one point because she yelled Come on! during a rally against Stosur in the second set.

Chair umpire Eva Asderaki docked Williams the point because she said the famous tennis star hindered Stosur's ability to complete a point. She instead awarded the point to Stosur which put her up 1-0.

When this happened, Williams went to Asderaki and said, I'm not giving her that game.

She continued to rant to the official and said, I promise you, that's not cool. That's totally not cool.

It got worse before it got better. During the changeover before the next game began, Williams went on to say to Asderaki, If I ever see you walking down the hall, you better look the other way...You are so unattractive inside. Who would do such a thing?...Giving me a code violation because I expressed my anger? We're in America!

As Williams was going on her rant, the crowd at Arthur Ashe Stadium in New York City began to boo. For many and possibly Williams herself, it was an episode of déjà vu.

In 2009, Williams famously went on an even worst rant at the U.S. Open during a semifinal match to Kim Clijsters. During that match, Williams was called for a foot fault that eventually led to her demise in the game. After getting called for that fault, she went on on a profanity-laced outburst.

Williams was fined $10,000 from the U.S. Tennis Association and $82,500 from Grand Slam administrator. She was on a probationary period for Grand Slam tournaments in 2010 and 2011.

It's unclear, what, if any, will be her punishment this time around. The World Tennis Association didn't give many details in a released statement.

Any impact this code violation might have on Serena Williams' grand slam probation would require the incident being ruled a major event. That determination will be made by the grand slam committee director, The WTA said.

Williams, after the match, acknowledged that Stosur outplayed her and it wouldn't have mattered anyway. She also said she wasn't familiar with the rule that cost her the point and said she got caught up in the moment.
