PALM BEACH GARDENS, FL (WFLX) - Palm Beach Gardens tennis star Serena Williams has to pay up because of her threatening tirade this weekend at the U.S. Open.

Williams lost it when a line judge called a foot foul during her serve. She walked over to the judge and threatened to shove a tennis ball down her throat!

She lost a point for the unsportsmanlike act, and that gave the match to Kim Clisters, who ended up winning the tournament.

So far, she's been fined $10,000. An investigation is under way to determine whether there should be additional punishment.

She was also docked $500 for smashing her racket, as well.
