More than $3 million in cars — including three Bugattis and three Rolls-Royce Phantoms — pulled up to Myles Chefetz’s Prime 112 in Miami when Floyd Mayweather Jr. arrived with an entourage 20 deep.

The scene the world’s highest-paid athlete created even overshadowed the celebration inside, where Chris Bosh, Ray Allen and Dwyane Wade toasted the Heat’s fourth straight trip to the NBA Finals.

The players had received a standing ovation after they quietly arrived.

Mayweather, who just called off a June UK tour due to visa issues, defended his good buddy Justin Bieber on Sunday, saying of the singer’s leaked racist joke tape: “We all make mistakes when we are young, it’s part of growing up.”
