Floyd Mayweather Hosts Birthday Bash At Versace Mansion, Gets Massive TMT Chain

Forget a club or fancy restaurant -- Floyd Mayweather celebrated his 48th birthday in ultimate style by throwing a massive party at the iconic Versace Mansion!!

The legendary boxer had the whole Miami Beach landmark to himself this week ... proving once again a guy like T.B.E. needs way more than 24 hours to honor his special day.

Mayweather set up shop at the 23,000-square-foot estate with his family and friends ... including Rick Ross (who performed!), Rich the Kid and Benny the Jeweler, who made Floyd's new iced-out chain -- which he personally designed and features The Money Team logo.

We're told the chain was a gift from Floyd's TMT family.

Mayweather also received a four-tier birthday cake ... which was seemingly designed to feature the New York buildings he recently purchased.

ICYMI, Mayweather bought the corner unit of 6th Avenue and 47th Street in Manhattan for over $20 million.

If Floyd didn't already have it all, he does now -- as he was also gifted a super expensive frosted diamond watch as a gift from Avi & Co.

The Florida takeover started last week for Mayweather's bash -- over the weekend, he threw an All-White Beach Party at Joia Beach.

R&B singers Jacquees and Rotimi performed on stage for the 50-0 boxer ... while his grandson, KJ, danced with him on the sand.
