Floyd Mayweather makes money rain down at Miami nightclub

They don’t call him “Money Mayweather” for nothing.

Floyd Mayweather lived up to his nickname by throwing $5,000 into the air at Miami hot spot E11EVEN, and then threw down even more dough on bottle service for his VIP crew Wednesday morning, an insider told Page Six.

We’re told the boxing champ, 41, arrived at the club around 3 a.m. in a Mercedes-Benz Sprinter dressed in a Nike hoodie, matching shorts and his headline-making $18 million Jacob and Co. watch.

Accompanied by a large crew of about 20 people, Mayweather was ushered in through the VIP door and seated at a secluded table in the club’s party pit.

“Within minutes of walking in, Mayweather started flooding the club floor with bills,” our insider said. “Clubgoers were going nuts realizing who it was after it happened.”

While the former fighter is known for not drinking alcohol, our source says “He didn’t mind spending his funds on his friends’ liquor,” and ordered multiple bottles of Grey Goose, Don Julio 1942, Moët Nectar Rose and Hennessy to his table.

After settling in with pals, Mayweather made money rain down on clubgoers once again.

According to our source, with the money he tossed carelessly into the air, plus his $6,000 bottle service bill, Mayweather shelled out $11,000 for an epically expensive night out on the town.

Also at the club was former FIFA World Player of the Year Ronaldinho, who arrived just after Mayweather made his exit at about 6 a.m.
