In the hot seat: How well does Andrey Rublev know the rest of the ATP?

WATCH: Before he reached the semifinals of the Nitto ATP Finals in Turin, Andrey Rublev was grilled on how well he knows his fellow ATP stars.

Andrey, uncensored. How well does Andrey Rublev know his fellow ATP stars? At the Nitto ATP Finals in Turin, Italy, we found out.

From whether or not Felix Auger-Aliassime plays the trumpet (He does!), to which player in the field was once in a One Direction tribute band (He pled the fifth, but we know the truth.), Rublev's body of knowledge on the random, off-court exploits of his peers was impressive.

But when faced with the question of whether or not Daniil Medvedev played the drums in his youth, Rublev was fooled, with hilarious results. Even when told he was correct answer.

"Daniil and drums?" an incredulous Rublev repeats when it's revealed it's a true fact about his good friend, "He lied to you, man. I am Elvis Presley if he played [the] drums. More people believe that I was Elvis Presley than Daniil played drums."

Watch the meme-worthy exchange, and Rublev's full inquisition, in the video below.

In his third appearance at the Nitto ATP Finals, Rublev went 2-1 in round-robin play to advance to the semifinals for the first time, where he finished his season with a loss to Casper Ruud. In group stage wins against Medvedev and Stefanos Tsitsipas, he rallied from a set down for victory.
