I don't think they've said one word to each other.
Last night Kyrgios and Tsitsipas played a doubles match together losing to Hurkacz and Stricker and tennis fans noticed the body language of both was not really great.
The duo shared a very intense match at Wimbledon earlier this year where tensions boiled over a couple of times. They continued their clash off the court but joked around stagging a rematch on social media. They got a chance to play together at the Diriyah Cup but they seemed quite frosty in the match not really talking to each other most of the time.
It's somewhat unusual for doubles pairings but it seems like there are some feelings there still after their Wimbledon match. A photo posted on social media showcased both players staring blankly during the changeover with the user noting that he didn't see them say one word to each other. Check it out below.
