Aryna Sabalenka came to the rescue of a parched fan during her Wimbledon semi-final against Amanda Anisimova.
The No 1 seed stopped the match to pass her water bottle to a supporter who was struggling with the 29C heat in the Centre Court cauldron.
Centre Court erupted into applause for the Belarusian star, who also carried over ice to help the heat-stricken fan.
It is not the first time this has happened at Wimbledon, with Carlos Alcaraz also providing for a spectator in his first-round clash with Fabio Fognini.
Sabalenka certainly didn't have to - she was 3-2 down in the first set at the time and could have taken the selfish route of focusing on herself.
But the selfless spirit prevailed in the three-time Grand Slam winner and she received her due plaudits on social media.

One said: 'Class'.
One commented: 'Kind gesture appreciated here.'
Another wrote: 'So many fans at Wimbledon are sat in the stands with no shade and many are not even wearing any sun hats/caps.
'The humidity inside Centre Court is so much more too. Remember to stay hydrated and take protection from the sun. Nice touch from Sabalenka.'
