"I didn't cheat on her with Nicola Liberova.

"She said, do you think so? But don't be fooled."

Bukovac reposted the interview to social media as fans questioned if the incident was nothing but a publicity stunt.

"Bro went 0-2 in one night - a double defeat," one user wrote.

"Why would you propose after a loss," another wrote.

Another added: "It's probably staged. Man loses then loses again, great for publicity."
