Despite an earlier report today (07-19-14) that quoted Floyd Mayweather saying he had sex with rapper T.I.‘s wife Tiny, the boxing champ vehemently denies making the comment.

Mayweather tells TMZ Sports … he really said: “he thinks I was f***ing his bitch.”

In the video, Floyd does try to mutter something before the sex line — but it’s hard to make out.

Mayweather adds, “I’ve never been with Tiny sexually. I respect her situation and I think she’s a good person. I would never disrespect a marriage.”

T.I.’s wife Tiny confirms that statement … telling us she’s never had sexual relations with Floyd — and thinks he only spoke out at the presser to get revenge for her BET Awards diss.

Here’s what T.I.’s saying about the situation:

“I hope he is enjoying himself. God bless him.”

Maybe it’s not conclusive that the boxing champ said he smashed Tiny, but there’s no doubt that he, once again, derisively referred to her as a “bitch.”
