Nick Kyrgios, who has a reputation for his bad-tempered antics on the tennis court, proved he's got a soft heart after all.

The Australian star followed up on his word to help people going hungry in the COVID-19 shutdown as several pictures surfaced on social media showing boxes of essential food packages ready for delivery.

Kyrgios wrote in an open letter last week, urging anyone struggling during the coronavirus pandemic to "not be embarrassed" about private messaging him if they need anything.

"Please don't go to sleep with an empty stomach," Kyrgios said on Instagram. "Don't be afraid or embarrassed to send me a private message. I will be more than happy to share whatever I have."

"Even just for a box of noodles, a loaf of bread or milk. I will drop it off at your doorstep, no questions asked!" he said.

"Hey guys, tomorrow I will be doing as many deliveries as I can throughout the day to the nearest people I have been in contact with," 24-year-old said in another post.

"If I haven't read your message yet, trust me I will do my absolute best to get to yours. And to my international friends around the world, I wish I could do more, but right now things are tough, stay strong, brighter days are coming."

Contrary to his public persona, Kyrgios participates in charitable activities on the ATP Tour.

In January, he led the way to donate 200 Australian dollars (125 U.S. dollars) for every ace he serves across all the events he played this summer to help victims of the Australian bushfires.

The move prompted Tennis Australia to announce a "Rally for Relief" event in Melbourne, helping raise almost 5 million Australian dollars (3.16 million U.S. dollars) for the Victorian Bushfire Appeal.
