Aryna Sabalenka is currently in a relationship with Brazilian businessman Georgios Frangulis, and the couple has been each other’s biggest supporters. Frangulis has been a regular presence in the stands, especially during Sabalenka’s victorious run at the 2024 US Open. In turn, Sabalenka has shown her support for Frangulis’s superfood brand, Oakberry, not only by promoting it but also serving as an official ambassador for the brand. Their mutual support highlights a strong partnership both on and off the court.

Aryna Sabalenka was previously currently dating Belarusian hockey player Konstantin Koltsov. He passed away tragically in an apparent suicide in March 2024. Sabalenka and Koltsov had just split before his death.

Sabalenka’s relationship with Konstantin Koltsov has raised a few questions. She was previously engaged to a mystery person whose name she would not reveal. But she did mention that her fiance was non-Belarusian. 

In 2016 Konstantin Koltsov announced his retirement from professional sports. In 1999, he was drafted by the NHL team, Pittsburgh Penguins. He last played for HC Dinamo Minsk in the Kontinental Hockey League. He represented Belarus in the  Winter Olympics and IIHF World Championships.

Though a singles grand slam title has eluded Sabalenka so far, she has two doubles grand slam titles. She won both titles with partner Elise Mertens but the doubles pair split in 2021 as Sabalenka wanted to focus on her singles career.
