There are a lot of sporting stars who are busy being filmed whilst getting drenched with icy cold water, Serena Williams, however, has been recorded warming up her vocal chords in front of a crowd.
The 32-year-old will begin her defence of the US Open crown next week but she has found time to display her talent with a microphone.
Together with fellow tennis star Jack Sock, Serena sang at a Karaoke event in New York, much to the crowd's delight, and she wasn't too bad either.
The world no.1 female star impressed while singing 'diamonds are a girl's best friend' and the video was later uploaded onto the 31-time Grand Slam champion's - singles and doubles combined - Facebook page.
Indeed it seems that the younger of the two Williams sisters is no stranger to singing, calling it her "favourite thing".
"I do like 80s, 90s rock because it's good for my voice," she said. "The thing about karaoke is picking a song that works for your voice, that way if you sing like a cat -- like I do -- you can still sound pretty good."
It would appear that Serena could match her competitors on the microphone as much as she can on-court, though the American probably shouldn't opt to change her career just yet - I certainly wouldn't if I had earned over $50 million in tennis prize money alone.
The five-time US Open champion will be hoping to add a sixth this year and with it a third consecutive title.
She will, however, need to right some of her wrongs that she has suffered thus far in 2014. The powerful player's best performance was at the Australian Open where she only managed to reach round four.
Disappointment at the French Open and Wimbledon was even more shocking. As well as a second round departure at Roland Garros, Williams was beaten at the third hurdle in the Wimbledon singles and then suffered with illness and suffered a bizarre capitulation in the doubles with sister Venus.
Despite those troubles though, Williams says she is fine are raring to go at Flushing Meadows: "I feel good. I feel good. I'm looking forward to it," she said. "I am going to be relaxed and enjoy myself."
US Open challenge
As an American girl, Serena is likely to be the crowd's favourite, but there will certainly be some tough challenges in New York.
Maria Sharapova is an ever-present threat and will hope to bag her second US Open title. Also in contention will be Wimbledon winner Petra Kvitova and the young Canadian prospect, who lost the SW19 final, Eugenie Bouchard.
Other top seeds include world no.2 Simona Halep, 2012 Wimbledon finalist Agnieszka Radwańska and 2008 French Open winner Ana Ivanovic - who, in fact, is still waiting for Serena to do her own ice bucket challenge after nominating her yesterday.
