His on-court heroics and rough and ready charm have won him a legion of admiring female fans.
And it seems none is keener on following the exploits of Scottish tennis ace Andy Murray than glamorous blonde Katharine Brown.
The pair has known each other since they were children, but while he has found fame as a sportsman; she has relied on her face and figure, recently becoming Miss Scotland.
Now the beauty queen is pursuing the 22-year-old player around the world in her quest to become a global celebrity.
She made headlines – and raised eyebrows among the notoriously close-knit tennis set – with her enthusiastic support for Murray at Wimbledon last month and then followed him to a tournament in Spain.
Now it appears she is planning a trip to the US Open this month in the hope of again sharing the spotlight with him.
But while it is clear that both have come through a great deal – they survived the Dunblane Primary School shooting massacre – it also seems that Miss Brown’s adulation of her ex-classmate is causing something of a stir in his four-year relationship with his sweetheart Kim Sears, 21.
‘Kim is fully supportive of Andy,’ revealed a friend.
‘But ever since this year’s Wimbledon she’s become more aware that he’s a sex symbol and is increasingly becoming frustrated by the constant presence of Katharine at his matches.’
Insiders say Andy’s mother Judy is concerned that his legion of female fans could detract from her ambitions for him to lift a US title.
‘Judy is fond of Katharine and they even teamed up with her on charity fund-raisers but since she won the Miss Scotland title, Judy’s concerned that the spotlight has been taken away from Andy’s tennis.’
Miss Brown – who is single and says she’s looking for Mr Right – has been open in her admiration of Murray, even appearing on television to address speculation.
The blonde, who won the Miss Scotland title in March said: ‘It will be great to go to New York and the US Open. I’ll go and hang out with them in New York, definitely.’
A spokesman for Murray said: ‘The family are very good friends with Katharine and she has been invited by Judy to go to New York.’
