Stefanos Tsitsipas has revealed his favorite thing about his girlfriend Paula Badosa in a US Open question and answer session hosted on the social media site Reddit.

World No. 7 Tsitsipas is preparing to compete at this year's US Open, where he will face Milos Raonic in the opening round on Monday, August 28.

Recently, the Greek player took part in a question-and-answer session ahead of the last Grand Slam of the season, where he responded to fans' queries about his girlfriend Badosa, as well as who he thinks is the most complete player on the ATP Tour.

Firstly, the 25-year-old answered a sweet question about his relationship with Spanish tennis player and former world No. 3 Badosa. A Reddit user asked what his favorite thing about his girlfriend was, to which he replied 'her intellect.'

The couple have been dating since May of this year and share a joint Instagram account called @tsitsidosa where they document their relationship. Unfortunately, Badosa has been forced to withdraw from the upcoming US Open and shut down the rest of her 2023 season due to a stress frature.

Tsitsipas then answered a question about who he thought was the most complete player on the Tour, saying that in his opinion, it is world No. 1 Carlos Alcaraz.

Finally, the Australian Open finalist was asked who his biggest supporter was, to which he replied by saying it was his brother Petros.

"My brother Petros. He always tries his best to be there for me and to ensure I bring the best out myself. He is honestly my rockstar! He cares a lot, and he means a lot to me," he wrote.
