We know what you're thinking - and yes, Floyd must have a very strong neck.

The champion stepped out one day after his 42nd birthday in Los Angeles, and he was surrounded boy bodyguards.

"Money" Mayweather was spotted by the paparazzi going inside "Ace Of Diamonds" ( AOD ) strip club in West Hollywood to continue celebrating his birthday. 

Given the current price of gold, the 25 pounds of gold that the champion wore around his neck has a value of more than $500,000. And that's not including the price of the hundreds of diamonds on the chains.

This past weekend was Floyd's birthday party and there was a little bit of drama...according to reports though, Floyd  says he ain't mad at Tyga for trying to pull a gun at his birthday party over the weekend -- in fact, Floyd says the rapper will still be invited to the next big bash.

TMZ broke the story ... Tyga was physically removed from Floyd's 42nd birthday party at the Sunset Room on Saturday night after getting into a heated altercation with another man inside the event.
