Being heavyweight champion of the world, it is inevitable to have a passionate fanbase, but one of Tyson Fury's fans has taken it to the next level.
The supporter showed his hero a tattoo of 'The Gypsy King's' face on his body, with the WBC champion then signing it for him.
"Someone tells me that you're an AJ [Anthony Joshua] fan, are you?" Fury asked the fan.
"No way," he replied.
Fury then asked the man to prove it and he lifted up his sleeve to reveal a huge tattoo of the boxer's face across his shoulder and upper arm, wearing a crown.
Fury then proceeded to sign the tattoo, saying: "So, I'm signing this man's tattoo, look. He's got me on his arm."
This all comes as Fury is in the midst of negotiations with Joshua ahead of a potential 'Battle of Britain' clash later in the year.
After Joshua was beaten by Usyk last month, 'The Gypsy King' had initially wanted to fight the Ukrainian for the undisputed heavyweight crown.

Usyk, however, made it clear he will not be returning to the ring until next year, as he needs to recover from various injuries and is keen to spend time with his family.
This caused Fury to offer Joshua a shot at his WBC world title and so far negotiations seem to be progressing quickly.
Fury has offered AJ a 60/40 split, which has been accepted, although Joshua wants the split reversed if he wins and the pair have a rematch.
One of the only other sticking points is that Fury has offered Joshua three dates in late November/ early December, but AJ's promoter, Eddie Hearn, has said that he will not be ready until December 17.
