Floyd Mayweather forgets to dress up as he poses next to superstar Mariah Carey at Halloween bash

FLOYD MAYWEATHER was the party pooper at Mariah Carey’s Halloween bash.

The retired boxer – reported to be worth $400million – was pictured at the Los Angeles party without a costume.

While superstar Carey stunned in an all red devil costume, Mayweather rocked up to the party in jeans, a t-shirt and trainers.

Interestingly he was pictured alongside rapper Tameka ‘Tiny’ Harris – with whom he reportedly had an affair in 2014.

Tiny is married to T.I., the Atlanta rapper who brawled with Mayweather at a fast food restaurant.

Mayweather and T.I. and their entourages were involved in a melee at a Fatburger in Las Vegas in May 2014.

The brawl happened after Tiny posted a picture of her alongside Mayweather’s daughter, sparking rumours of an affair.

Witnesses said that T.I. – real name Clifford Harris – approached Mayweather in the restaurant, verbally abusing him and allegedly throwing a punch.

Claims were made that Mayweather said to Harris: “control your b**** motherf*****”.

Also at the bash was actor Nick Cannon and old school rapper Master P.
