On court tension apparently got the better of Andy Murray's fiancée Kim Sears today when she seemingly hurled an expletive-filled shout from the stands at the Australian Open.
Kim, 27, sparked huge reaction from tennis fans when she appeared to mouth the words "f***ing have it" during Murray's semi final clash with Tomas Berdych.
Footage showed the heated moment in the stands when Murray broke back in the first set.
She glared towards Berdych's team as she responded to Andy's enthusiasm on court after winning the key game.
Kim also appeared to fire further expletives at Murray's Czech opponent Tomas Berdych, who dumped Rafael Nadal out of the tournament in the previous round.
Murray defended his fiancée and said: "In the heat of the moment you can say stuff that you regret."
One tennis fan wrote online: "Great win for Andy. I'm no lip reader but what did Kim Sears say? Not very ladylike!"
Others said her outcry was "a bit out of order."
Andy went on to beat Berdych in four sets to reach the final of the tournament.
Former British tennis star Anne Keothavong praised Murray for "the best on court interview" after the match.
