Andy Murray girlfriend Kim Sears caught during outburst

No one could deny that the Australian Open semi-final against Tomas Berdych was tense but it wasn't just Andy Murray who was putting his heart into the affair.

The Scot is no stranger to outbursts on court but on this occasion his fiancee Kim Sears got in on the act with what appeared to be a lot of effing and jeffing in the direction of Murray's Czech opponent.

It certainly excited the attention of Twitter with the former British No1 Anne Keothavong among those retweeting the vine and adding the perhaps appropriate comment: "f****** hilarious!"

It is not the first time player's other halves have got carried away with the action. In November the Australian Open champion Stan Wawrinka was apparently called a "cry baby" by Roger Federer's wife Mirka after he appeared to indicate she was disrupting his concentration by talking too loudly, prompting an on-court row at the O2 Arena.
