Floyd Mayweather & Tiny Cheating Rumors Denied: TI Epic Brawl 'Diss,' Wife's Instagram Rant Supports Boxer's Viral Response/Apology!

TI allegedly suspects Floyd Mayweather of hooking-up with his longtime "Family Hustle" wife, Tameka "Tiny" Cottle. But according to the infamous boxing champ, such cheating rumors are simply untrue. The "Dead and Gone" rapper and his homies had no reason to "attack" in Las Vegas. But Mayweather does have something to apologize for - calling Tiny a "b*tch." And apparently, the Xscape songstress is still on his side!

UPDATE: Floyd Mayweather Strip Club Extravaganza After TI Brawl [WATCH]

Check out Mayweather's rather lengthy response to the epic Fatburger "showdown," as reported exclusively by NecoleBitchie.com. Yes, the fight was definitely over drama dealing with Tiny:

I been knowing Tiny before T.I. I've never slept with her, I never kissed her, never touched her in no inappropriate way. Her friend Shekinah wanted to come to the [May 4th] fight, she brought Tiny with her. They came to the fight. After the fight was over Saturday night, Sunday they came over my mother's house. My mother had a big, big party for me. They came over and showed love. They came over to my house all cool, all respect. Hang out with The Money Team, my crew. Everybody was cordial. No disrespecting type. After that, I guess she put a picture up on Instagram of her at the fight so I guess he [T.I.] was feeling some type of way.

[T.I] came to me when I was in New York. He stepped to me when I was at the jewelery store like, 'Yo, let's go outside and talk.' We went outside to talk, but he talked about, basically, 'These girls tryna play us against each other.' I said, 'I don't know what you're talking about. You're talking about your wife?' I never put up a picture of her on Instagram, Twitter or Facebook. I was basically like, 'Listen. I'm letting you know I ain't got...me and your wife don't have nothing...if you think so. So Memorial Day weekend, a lot of people come out to Las Vegas. Tiny and Shekinah was out here. They come to my party last night. They cool. Everything is cool. We was at the strip club. Everything was cordial. We having fun. I throw my daughter [Iyanna] a big [14th] birthday bash today.

I'm eating at Fatburger and next thing you know, he walk in talking about we need to talk again. And then I told him, 'You need to get the f*** outta my face. That's what you better do.' And then he said, 'I ain't talking to all these people so you ain't gotta talk loud.' I said, "Listen, don't come to my face with no disrespectful sh*t. Like I told you before, you must've forgot what I did for a living.' He said, 'You do in the ring, I do it in the streets.' I said, 'My man, I do it everywhere. You can find out if you want to.' Just like that.

Then a couple of words exchange and people got to pushing and a riot kinda broke out. And then a bunch of chaos and that was basically it. Because, like I said before, he probably does some foolish things, but he ain't no damn fool to swing on me. Like, you must've forgot what I do for a living. He had a totally different look on his face.

Only person I wanna apologize towards is Tiny. I said something like 'control your bitch' and I don't want to say that about Tiny. So I do apologize to Tiny because she cool people, man. She cool. She never been disrespectful to me. Shekinah never been disrespectful to me. I'm going to continue to support Tiny and Shekinah cause they're cool people and I don't got nothing against them. So I apologize for that.

I'm not sleeping with that girl [Tiny] and I told that man before. But if I was, talk to her about that, don't talk to me about that. But I'm not going to be disrespectful because I'm not going to sleep with a married woman. Now if she was divorced...I still wouldn't do that because I'm cool with her and we have a real cool and cordial relationship and sometimes sex can mess a good friendship up. And basically, I don't want to f-ck up a good relationship that I have with a person. So whatever I said, 'stole your b*tch...take your b*tch" or whatever, I apologize to Tiny and all of her children and T.I.'s children for saying that. I want to apologize to the children and Tiny and Tiny's family for saying what I said.

As far as him swinging on me, I ain't having that. You see me. I'm out all night. He didn't make an appearance so let's see how his face look. My daughter had a birthday party. Tiny is married. I respect that. I don't care if y'all separated, she's still married under God's eyes and the law. I'm not going to sleep with a married woman. I'm not going to do that. Like I said on All Access, I'm becoming a better person.

So, that explains that.

And Tiny's response? Well, she doesn't seem to stick-up for her hubby...

An Instagram fan asked what she thought about Mayweather's apology, and she wholeheartedly accepts it. In fact, TI was the one "out of line!"

Majorgirl writes to cyber haters:

"I ain't put that ni**a in sh*t!! U see that ni**a in the media with different b*tches, don't come at me with that sh*t about no pix with a friend... f*ck you and who ever feel like you!!!"
