Tennis star Andy Murray came through a tough set to beat his Czech opponent Tomas Berdych at the Australian Open yesterday, but it was his fiancée Kim Sears that made headlines.

Kim got a bit too wrapped up in the tension of the game and was caught on ESPN cameras wildly cursing as she watched the match.

Although no microphones caught her f-bombs (phew), it's clear she was not singing Tomas' praises:

Lip-readers have deciphered her outburst as "'F***** have that you Czech flash f***" or something close to it.

Ouch.

When asked about Kim's f-bombs, Andy didn't seem too bothered, saying, "I was told about that. When there’s a lot of tension surrounding something which you [the media] created, then it’s completely normal that the whole first set everyone was tight… In the heat of the moment you say stuff that you regret."

We absolutely agree, Andy, we're just glad our rants have never been caught by international TV cameras!
