There's nothing like a bit of an embarrassment from your mum, and even though he's a two-time Grand Slam champion - Andy Murray has learnt that he's not too far away from the firing line.
The 27-year-old is used to hearing his mother, Judy, who is a big figure in British tennis, talking about him in various interviews, but she may have crossed the line this time.
Exercising in hot countries, especially for a Scottish-born man, is always a sweaty venture and a certain musk is associated with it. What Andy didn't need was his mother blurting to the press about his smelly feet, messy nature whilst lauding his brother Jamie.
"Andy has got the smelliest feet and he's very untidy, and Jamie is tidy," Judy said in an interview on Radio 4.
"They are so different from each other in so many ways."
This isn't, however, the first time that Murray has been left cringing by comments from his mother. The 54-year-old is almost always in attendance of his big Grand Slam games, but off-court she can be a hindrance rather than help.
In 2011, she sent flirty tweets to fellow hitter Feliciano Lopez - calling him 'Deliciano' and admiring his muscular physique on-court.
It prompted her son to hit back: “I think it’s about time she stopped that nonsense. It’s making me throw up. It’s disgusting."
The latest comments may lead to Murray being alienated by his fellow pros. Practicing in Miami is only likely to extenuate the smelly feet problem ahead of the hard-court season and following US Open in August.
The world No.10 will hope there's an advantage to be found though, maybe the likes of Roger Federer, Rafael Nadal and Novak Djokovic will fear going to the net in case of catching the whiffy scent.
You'd figure that girlfriend Kim Sears has had time to try and deal with with the issue, but less impressed will be coach Amelie Mauresmo and other members of Murray's entourage. The Frenchwoman is extending her spell with the British no.1 despite a tough time at Wimbledon, perhaps the first way to move forward would be a foot spa.
At least with Judy's latest revelations, Andy can reflect on his competitive rivalry on Jamie fondly. The elder brother may be tidier, but the 28-year-old hasn't managed the same levels of on-court success.
Jamie never established himself as a singles player - his best world ranking was 834 - and instead forged a career in the doubles. He actually managed a Grand Slam triumph before his brother; at Wimbledon's mixed doubles - with Jelena Jankovic - in 2007.
Since then, though, Andy has become a global star of the sport with singles majors at the 2012 US Open and Wimbledon last year - the first British man to achieve that feat in over 70 years.
