Andy Murray's girlfriend Kim Sears has revealed that she becomes nervous when she watches her boyfriend Andy Murray play big matches.
Talking on a BBC show 'Andy Murray: The Man Behind the Racquet', which will be aired on BBC1 on the eve of Wimbledon, she said that during Murray's big matches, she looks calm from outside but inside it's definitely a different story, the Sun reported.
This is the first time Kim spoke publicly since they started dating in 2006.
