Serena Williams FLIPS out at US OPEN... epic!

Serena Williams is one of the top female tennis players in the world. Her and sister Venus Williams are definitely a forced to be reckoned with on the court, but in a bizarre turn of events, tennis star Serena Williams completely lost it on Saturday at the US Open after being called on a rare foot fault. It was match point and a judge called her out on the foot fault.

That's when Williams, a three-time US Open winner, lost it, approached the judge and, according to the Associated Press, shrieked at the official, “If I could, I would take this … ball and shove it down your … throat." Day-um.

This was deemed unsportsmanlike and Williams was deducted a point, which, because it was already match-point, cost her the match. Her opponent, Kim Clijsters, was unranked and unseeded prior to the freak upset.

She now moves on to the next round.
