QUEENS, NEW YORK: The late-night US Open round of 16 encounter between Jannik Sinner and Alexander Zverev, who is allegedly madly in love with his model girlfriend Sophia Thomalla, was marred by a racial epithet directed at the No. 12 seed from Germany.

When Zverev and Sinner were locked in a thrilling fourth-round tie in the wee hours of the morning in New York, the former complained to the umpire about something he overheard just before a point.

"He just said the most famous Hitler phrase there is. It is unacceptable," Zverev, who was born in Hamburg, informed British umpire James Keothavong after hearing a slur from the audience.

Zverev revealed to a reporter what the alleged fan had shouted after the game.

"He started singing the anthem of Hitler that was back in the day. It was `Deutschland über alles' and it was a bit too much," the Hamburg native who is in a relationship with the German actress Sophie Thomalla stated, as per Daily Mail.

Online fans have been intrigued about Zverev's private life ever since he made the news about the "Hitler phrase."

Alexander Zverev's girlfriend Sophia Thomalla is currently in New York to cheer on her beau at the US Open and might have witnessed the incident too.
