Floyd Mayweather hits Gold Rush in Miami for birthday

Floyd Mayweather made it rain singles for his 45th birthday this week — tossing out thousands at a Miami strip club, a source tells Page Six.

A spy said that the champion boxer — known as “Pretty Boy” or “Money” — celebrated his birthday with a group of 20 pals, including Rams footballer Aaron Donald, by hitting up jiggle joint Gold Rush.

“Thousands of single bills were escorted to their table along with a parade of bottles,” says a spy, who noted that Mayweather does not drink, but that his pals enjoyed the bubbly and Don Julio 1942 tequila.

We hear that the group partied till 4 a.m.and managed to plunk down $30,000 for the booze and dance-filled night.

Mayweather had been spotted earlier at Sushi Fly Chicken. According to TMZ, a karaoke machine was brought out and video online showed the boxing great being joined on the mic by Kanye West and ex-Buccaneers star Antonio Brown.

Mayweather, West and Brown last made headlines in January when they hung out with Madonna at Delilah’s in Los Angeles while West was dating “Uncut Gems” star Julia Fox.

Mayweather dropped $18 million on a 9-bedroom, 10½-bathroom Miami Beach mansion back in August, adding to his extensive list of real estate holdings — including a $26 million estate in California with a wine wall, and a $10 million Las Vegas mansion.

Back in April, he was spotted spending $80,000 on Hermès Birkin bags at luxury resale store Privé Porter in Miami.
