Rousey was out in NYC Monday night -- where she told us there's still hope for Floyd ... "He could go the Mike Tyson route and go on a journey of self betterment."
Mike had serious issues of his own during his storied boxing career -- his arrests include drug possession and rape. But people like Ronda truly believe he's a changed person now and he's completely rebuilt his image.
And according to Ronda ... Mayweather could do the same -- if he wants to.
There's more ... we also asked Ronda about her upcoming gig hosting ESPN's "SportsCenter" (she's pumped), and how she feels about Cher defending her UFC pal Nick Diaz, who was recently suspended for weed.
"I thought [Cher] was cool ... I didn't know she was THAT cool!"
'League' star Steve Rannazzisi admits he did a "terrible" thing by lying about 9/11, but says the lie was not premeditated ... it started at an off the cuff quip at The Comedy Store.
Steve went on Howard Stern's show Tuesday and explained his lie ... that he was in one of the Twin Towers during the attack and it became a life-changing moment that led him to pursue his career in comedy.
According to Steve, he was just asked by someone at the club where he was during the attack and the phony story just spilled out. He says once that happens you have 15 seconds to say it was BS or else you have to own it.
It's a really good interview. He says he chose to talk about his lie on 'Stern' because Howard personifies New York and felt it was the right venue.
"Empire" star Jussie Smollett is keeping it as real as his TV mama Cookie does ... saying he's NOT hookin' up with Michael Sam ... despite the fact they've been spending A LOT of time together recently.
Just last week, Sam posted 3 PICS with Smollett on social media ... leading some people to believe they were more than just friends.
But when we saw Jamal Lyon working out in L.A. on Monday, dude wanted to set the record ... er, straight -- they're close, but ain't nobody humpin' around (shout-out to Bobby Brown).
BONUS -- Smollett also responded to 50 Cent, who's been BLASTING "Empire" over social media ... but surprisingly, he didn't fire off a Lucious Lyon style retaliation. Instead, he's killing with kindness.
Ex-NFL star Kordell Stewart says he NEVER dated gay Internet star Andrew Caldwell -- the guy who famously declared "I'm not gay no more!" -- telling TMZ Sports, "I'm a heterosexual man."
The rumors started when Caldwell went on a radio show last week and proclaimed the two were in a secret relationship ... and Stewart bought him everything from purses to expensive cars.
But Stewart tells TMZ Sports ... Caldwell is simply delusional -- "I don't know the guy. I've never heard of him."
"There's no room in my personality for that lifestyle. It's not what I believe in. I'm a heterosexual man."
As our friends at BSO pointed out, Caldwell shot to cyber-fame last year when he denounced his homosexuality onstage at a St. Louis church -- saying, "I'm not gay no more. I am delivered. I don't like mens no more. I like women. Women, women, women, women!"
Stewart says he believes Caldwell has defamed him -- but when asked if he plans to sue, the ex-Pittsburgh Steelers star says he's not sure yet.
Shaquille O'Nealjust made his case for inclusion into a very elite group ... The Fugees ... 'cause The Diesel just brought the house down in Miami ... hitting the stage to sing "My Girl" with Wyclef Jean.
Jean and O'Neal were at Barry University for their 75th anniversary "Birthday Bash" Saturday night where Jean ... of course a world famous musician ... was giving a special performance.
The performance got extra special when O'Neal ... a world famous cut-up ... crashed the stage to join Clef in a performance of the Motown classic "My Girl."
Check out the clip -- Shaq doesn't quite know the lyrics, but it doesn't stop him from swaggin' his way through Smokey Robinson's words with a little assist from Wyclef.
Bonus -- We also got video of Wyclef performing "Hips Don't Lie" later in the night.
