Ordinarily, any sports celebrity would be more than willing to give their autograph to fans. But in the case of Floyd Mayweather Jr., it seems the retired boxing great has a certain "no-sharing" policy in play -- meaning if a fan wants his autograph, it should be only him on the item where it would be signed and no one else.

It appears this is the new rule in place for the Flamboyant One when a female fan asked for his autograph last weekend during the Manny Pacquiao vs. Keith Thurman fight in Las Vegas. According to a report from TMZ Sports, Mayweather initially grabbed the glove and was ready to sign it. However, after inspecting it, he saw several other names (undisclosed) who signed and pulled back.

"You already got some names on it, baby. You gotta have gloves with just me on it!!"

Without question, Mayweather wants to be in a class of his own - yes even when it comes to signing autographs. What remains unclear is if this was situational - meaning the 42-year-old may have not been in the mood with all the attention on Pacquiao and Thurman plus some other boxing greats in attendance at the MGM Grand in Las Vegas.

Mayweather witnessed how Pacquiao pulled off a split decision win over Thurman last weekend. And with him in attendance, it came to no surprise that murmurs of a potential rematch with the Filipino boxing icon cropped up. Mayweather answered back to critics via his Instagram account, reiterating that he has little to no interest of a second bout.

"For years, all you heard was that 'Floyd is afraid of Manny Pacquiao.' But what's funny is, when we finally fought, I won so easily that everyone had to eat their words! All of the so-called boxing experts, critics and jealous American 'fan base' either went mute and ran for cover or made every excuse in the world as to why I should give Manny Pacquiao a rematch," part of Mayweather's response said.

Of course, all this reached Pacquiao and the eight-time division champion had a response of his own.

Right now, Mayweather continues to enjoy his retirement and focus more on doing business. The last time he stepped into the ring was against Tenshin Nasukawa on December 31 which ended in a TKO victory for the Flamboyant One where he reportedly earned $9 million for the fight.
