Serena Williams has crashed out of the US Open after serving up a volley of abuse to a line judge during her semi-final against Kim Clijsters.
The Belgian player was just two points from victory when a line judge called out Serena on a foot-fault, making it match point for Clijsters.
Serena launched an angry outburst at the official and was penalised by a point, helping Clijsters win 6-4 7-5.
Clijsters will now face Caroline Wozniacki in the final.
Afterwards, the defending champion said she couldn't remember what she'd said, but she wasn't happy.
Kim Clijsters said she faced the other way during the row to stay focussed
"It was in the moment," she said. "It was a really crucial point. I haven't really thought about it to have any regrets.
"I didn't think I would get a point penalty, I didn't think about it."
She said she hadn't had a foot fault all year and was surprised to get foot faults in the tournament.
"I'm not saying I don't foot fault, but it was what it was," she said.
"I've never been in a fight in my whole life so I don't know why she would feel threatened. I'm clearly not happy."
