Editor’s note: The latest version of this article was updated to reflect Alexander Zverev’s reported relationship status.
German tennis player Alexander Zverev has taken the world by storm over the last few seasons, skyrocketing up the Association of Tennis Professionals (ATP) and challenging some of the sport’s biggest names. He is currently the world’s No. 4-ranked player.
Given Zverev’s platform and success, there is a lot of interest in his personal life. And while the Olympic gold medalist has still never won a major in his professional tennis career, he’s certainly winning off the court.

There had been speculation that Zverev was dating fashion influencer Caroline Daur. This stemmed from rumors that Zverev had broken up with Sophia Thomalla, who is an actress and model. The couple had been together since 2020 but were initially thought to have split at some point in 2025.
These rumors began once photos surfaced of Zverev and Daur (who is 30 years old) seemingly enjoying each other’s company at the Australian Open, where Thomalla was nowhere to be found.

Caroline Daur Turns Heads in Black Bikini Selfie Amid Miami Open
Zverev is currently competing in the 2026 Miami Open. He advanced to the Round of 16 with his win over Marin Ċilić on March 23, and is not slated to face Quentin Halys of France on March 24.
Daur is currently in Miami. This was made clear by an Instagram post she made on March 22, which featured several photos from her recent trip. Several of them show her in a black bikini, which is sure to turn heads.
The post was captioned, “hi miami 🫰🏼”.
Among some of the other photos included are her sitting at the beach in a white outfit, her standing next to a boxing bag after what appears to have been a successful workout, several other photos of her out to eat and with friends on the beach, the definition of a laptop, a rose, some sushi, and several other bits of content that show the 30-year-old is enjoying her time in South Beach.
There has been additional information to suggest that Zverev is still dating Sophia Thomalla, which means that Daur is either just following the Open or is dating somebody else.
One would imagine that Zverev is primarily focused on the court at this point, as his work is cut out for him if he wants to succeed at the Miami Open. Regardless, Zverev has become must-see TV for any tennis fan.
