Floyd Mayweather Buys His Infant Grandson A Diamond Encrusted Rolex!

'KJ's papa got him his first Rolex," the caption read.

In a stunning shot, the baby's wrist can be seen wearing the tiny diamond-encrusted Rolex watch with his famous grandfather holding up the face so you can see it shine!

Of course, several of the comments are pointing out how unnecessary the purchase is for an infant -- who can't appreciate it. Not to mention, he will grow out of this one in the next few months. But, he is just following in the family's footsteps by always being iced up in a dope watch.

It should be noted, baby Kentrell's famous grandfather is quite the watch collector himself -- owning one piece worth over $18 MILLION!

During a recent interview, Floyd revealed he travels with an entire case of watches, so he can change them out on each day that he is out of town. "Now if I go on vacation, my fault, when I go on paycation for 30 days, I take 30 watches with me. But you know what, what’s crazy is this: If we add 10 more days, I take 10 more watches," he said.

Adding, "But then I say, ‘f--k it,’ if I want to bring out the one and only, then I bring out the watch that costs $18 million.”

BTW -- Floyd Mayweather can afford it.

The boxing legend is one of the highest-paid athletes in the world, earning over $1 BILLION in his career -- including over $300 Million for a single fight against Manny Pacquiao. He also made another $300 Million fighting Conor McGregor.

As for the $18 Million diamond watch, it was made by Jacob & Co. and features 239 emerald-cut baguette diamond stones, each of them weighing in at three carats. Sorry, dad, we know this is a lot to follow for the baby's first birthday party!!
