Mayweather splashes out $18,000 on car seat for grandson 

Boxing legend Floyd Mayweather has demonstrated once again why he is the coolest grandad in the world.

The unbeaten boxer, 45, became a grandad early last year when daughter Yaya welcomed her first child with rapper NBA Youngboy.

Mayweather has made millions from exhibition bouts since hanging up his gloves in 2017.

And plenty of that money has gone on fast cars, expensive jewellery and huge houses.

Mayweather showed off his extravagant $350,000 Rolls-Royce last week - but couldn't have one-year-old Kentrell Jr missing out on all the fun.

According to TMZ, the 50-0 star has bought the tot an $18k car seat - specially lined with MINK fur.

Mayweather got the lavish seat - which comes complete with a name badge - from old pal Obi Okeke aka Dr Bugatti.

The recliner is custom-made to fit in Money's 2022 Rolls-Royce Cullinan, which features a twin-turbo 6.7-liter V12 engine and tops out at 160mph.

And the fur lining matches perfectly with the rest of the whip's interior, ensuring baby and grandad will ride in maximum comfort.

When the 45-year-old became a grandad for the first time last year he initially suggested he wouldn't be a hands-on grandpop.

Floyd said: "I want the best for my daughter. I always want the best.

"If that makes her happy, then we’re happy. Her mother (Melissa Brim) and I are happy.

"But, what I try not to do is get in her personal business. Because once she’s no longer under my roof, you know what, it’s between her and her better half."

But within five weeks, he had wasted no time spoiling his newborn grandson rotten - buying the tot a diamond-encrusted Rolex.

While Kentrell Jr watched on in awe as his grandfather sparred ahead of his exhibition bout with Don Moore.

Mayweather is reportedly planning a stunning $200m return this year - to put his 50-0 record on the line.

And recent videos have shown he still has the reflexes to fight at the very top - despite hanging up his gloves five years ago.
