Tiafoe takes on the world No 2 in the Australian Open quarter-finals this morning.
The young American, who celebrated his 21st birthday on Sunday, is in unchartered territory after reaching the last eight of a Grand Slam for the first time in his career.
Following all four of his wins in Melbourne, Tiafoe has celebrated by doing James’ ‘The Silencer’ on court.
And when ESPN published a video comparing James and Tiafoe’s celebrations on Instagram, the Los Angeles Lakers star commented with two muscle emojis.
The reaction shocked Tiafoe who is a big fan of the NBA legend.

“I told my coach, Zack Evenden, my agent, Alex, 2019 I’m going to pop off.
“No reason why I can’t do these things. I didn’t think it was going to happen right away. This is unbelievable, man.
“Don’t get that excited Let’s not get ahead of ourselves here.
“Like, I don’t know if you saw, ESPN put a pretty cool pic of me and him – well, video of us doing his celebration.

“He commented silencer and he put a crown, two muscle emojis.
“I was like, clearly he knows who I am now. I was like, That’s just crazy.
