got into the Halloween spirit by dressing up in a hilarious costume which had fans laughing on social media. The two-time champion is known for his deadpan humour, which was on full display as he dressed up as a grumpy clown.
Murray shared a picture of his costume on , showing him in white face paint and a multi-coloured wig. He also wore a red nose, a red and yellow polka-dot top and some comically wide green trousers held in place by suspenders.
With an expressionless look on his face, the father-of-four captioned the post: "Hope you are all enjoying Halloween as much as me."
Murray's post received hundreds of responses from delighted fans, with @deepfriedlard joking: "You've gone to a deep, dark place since retirement, Andy."
@paulofaria_ said: "It is absolutely impossible not to love this man," while @gillianspalding added: "I feel like this is why Instagram was invented."
"He's gone dressed as the Scottish goalie," quipped @lordbertilakunofficial as @thefitnesschef_ joined in on the fun with: "The psychedelic sequel to Wallace and Gromit (the wrong trousers)."
Murray's post also piqued the attention of former Davis Cup team-mate Neal Skupski, who said: "Such a clown," while the official Cincinnati Open account posed the question: "Is everything ok, Andy?"
Others pointed out that Murray's choice of colours would have seen him barred from Wimbledon. His mother Judy also chimed in, reposting the image on with the caption: "This is what happens when you have too much time on your hands."
Murray appears to be enjoying life in retirement after playing his final tournament at the Olympics in the summer. He recently insisted that he was not missing tennis, saying that he felt 'really free' and underlining his desire to spend more time with his family.
"Since I've stopped, I feel really free and have got lots of time to do whatever it is I want," he told . "I can dedicate time to my children and have free time to play golf or go to the gym on my own terms. It is really nice and I didn't expect that.
"I was expecting to find retirement hard and be missing tennis a lot and wanting to get back on the tennis court on tour. So far it has been the complete opposite to what I was thinking."
