Floyd Mayweather buys five-week-old grandson a diamond-encrusted ROLEX as doting, millionaire grandad splashes the cash

FLOYD MAYWEATHER has wasted now time spoiling his new-born grandson rotten – after buying the five-week-old a diamond-encrusted ROLEX.

Last month, Money’s daughter Yaya welcomed Kentrell Jr to the world along with rapper NBA Youngboy.

Floyd Mayweather has bought his five-week-old grandson a diamond-encrusted RolexMayweather also recently took Kentrell Jr on his first trip on a private jet

And at just five weeks old, the infant is now the owner of a fully-iced watch and has even taken a ride on a private jet.

The astonishing timepiece appears to be a Rolex Oyster Perpetual Datejust, with prices starting around £32,000.

However, baby’s first watch appears to have been fully customised to have diamonds encrusted on the band as well as the circumference of the face, which could push the cost into six-figures.

Tagging her dad in the post, Yaya took to Instagram to show off KJ’s new gold and diamond bit of bling.

Yaya captioned the snap: “KJ’s papa got him his first Rolex.”

Mayweather‘s extraordinarily generous gift is hardly out of character, though.

The 50-0 boxing legend, 43, has an extravagant watch collection of his own, with one piece costing an eye-watering £13.8million by itself.

In a recent interview, Money claimed: “Now if I go on vacation, my fault, when I go on paycation for 30 days, I take 30 watches with me.

Mayweather has at least 41 diamond-encrusted watches in his outrageous collection

One of Mayweather’s watches – the Jacob and Co Tourbillon ‘Billionaire’ – is worth £13.8m

“But you know what, what’s crazy is this: If we add ten more days, I take ten more watches.

“But then I say, ‘f*** it,’ if I want to bring out the one and only, then I bring out the watch that costs $18m (£13.8m).”

Mayweather bought the show-stopping timepiece after his 50th career win, where he beat Conor McGregor in a money-spinning Las Vegas showdown.

The American legend is believed to have pocketed around £300m for the win, spending a mere fraction on the Jacob & Co Tourbillon watch, dubbed ‘The Billionaire Watch’.

Incredibly, Mayweather has 41 diamond-encrusting watches in his ever-growing collection.

The watches are estimated to be valued at a combined total of £20m.

Meanwhile, Mayweather’s return to the boxing ring has been delayed.

Money was due to face YouTuber Logan Paul on February 20 in an exhibition spectacle.

But it has since been backdated with a new date yet to be confirmed.
