Just hours before Jose Canseco allegedly committed rape ... the alleged victim posed for a very flirty pic with J.C. in a Vegas casino and joked that they had just gotten married, TMZ has learned.

The pic was taken on the floor of the MGM Casino at 2:51 AM on May 10 -- with the woman cozying up for a couply shot with Jose ... with her open right hand placed on the center of his exposed chest.

The person who took the photo says he's a huge Canseco fan (apparently those still exist) ... and had recognized Jose strolling around the casino with a female companion.

The fan asked Jose if he could snap a shot -- and Jose obliged, striking a pose with the woman while she giggled and told the photog she and Jose had just tied the knot.

For the record -- we've done some digging, but couldn't find any proof of a Canseco marriage.

The photog told us the two seemed happy ... no signs of distress.

Of course, things changed -- 'cause the woman reportedly told police Jose drugged and raped her later that day.

Jose has denied the allegations -- claiming his accuser is making up the story for publicity.

Steve Nash is making a full-court press to block his ex-wife from moving from Phoenix to L.A. with their 3 kids so he can avoid paying child support ... this according to court docs filed by his ex.

Nash and his ex Alejandra are locked in a legal battle royale over where she's allowed to move.  Alejandra wants to relocate from Phoenix to L.A. ... so the kids can be closer to Steve.   But the b-baller has vigorously tried to block the move, which is curious because he famously chose the Lakers over the New York Knicks to be closer to the youngins.
 
Alejandra says Nash has told her he didn't want her to move out West because he might be traded or forced into retirement ... which would mean uprooting the family again.

But Alejandra says Nash is simply blowing smoke -- and that the REAL reason he wants her to stay put in PHX is because California courts are likely to impose huge child support obligations against him -- something the Phoenix courts have not done.

Alejandra claims Steve is not paying a cent in child support ... zip, zero, zilch ... and he doesn't want to blow a good thing.

Alejandra says Steve's admitted that living so far from the kids is tough on him and them ... and it would be better for everyone if they could spend more time together ... but his desire to save a few bucks on child support is trumping his obligation to his family.

For now ... a judge has issued a restraining order, prohibiting Alejandra from moving West until their trial, which is scheduled for next week.

Some racist jerk has desecrated Michael Clark Duncan's grave ... this according to a Duncan family rep, who tells TMZ a vandalism report has already been filed with the police.

We're told ... a family friend stopped by Forest Lawn Cemetery in the Hollywood Hills to deliver flowers to the spot where MCD was interred in Sept. 2012 ... when she noticed a figure of a cartoonish black face had been attached to the center of MCD's tomb.

The friend believes the black face is an image of "Sambo" -- a character that has long been considered an offensive and racist depiction of a black person.

MCD's friends and family were shocked by the discovery -- wondering what kind of lowlife would desecrate Michael's final resting spot.

We're told the family contacted the LAPD -- and were told the incident could be considered a hate crime. Cops are currently investigating the situation. 

The family tells us ... Forest Lawn immediately removed the "Sambo" from MCD's tomb -- but they won't be satisfied until they find out who violated the tomb.

"Baywatch: The Retirement Years" would be an awesome show ... because TMZ has learned, 60-year-old David Hasselhoff just bought himself a brand new mansion for $1.95 million.

Sources close to the deal tell us, Hoff purchased the 5,767-sq.-ft. Mediterranean home in Calabasas last week.

The 5-bedroom, 6-bathroom house sits in a small gated community ... and it's even got its own basketball court.

Perfect timing for Hoff -- he just sold his bigger house in Encino, which he listed last November for $3.795 million.

It's thick, round, wrapped in stripes ... and a total mystery. But just as TMZ's investigative team attempted to put a name to that sweet rear -- someone cracked it wide open. The mystery ... that is.

Charlie Sheen has decided he's WAYYY too Caucasian to star in the new "Machete" movie -- so he's channeling his Latino roots and changing his name back to Carlos Estevez ... at least for now.

TMZ obtained a screengrab from the upcoming flick ... which shows Sheen will use his birth name in the new Robert Rodriguez joint. It's the first time in his professional career he won't be billed as Charlie Sheen.

It makes sense ... Rodriguez films often celebrate Latino pride (think "El Mariachi," "Desperado," "Machete") so Sheen is just getting into the spirit of the campy thriller about a rampaging Mexican assassin.

A little history ... Charlie Sheen’s dad Martin Sheen was born Ramón Antonio Gerardo Estevez, from his Spanish father's side. He made up "Martin Sheen" to get acting jobs but never changed it legally ... passing "Estevez" to all 4 kids.

Martin has said he regrets not sticking with his real name ... so this TOTALLY counts as a son-redeems-the-father story, right?

Sad ...

  

Jose Canseco's ex-GF tells TMZ ... she believes J.C. is COMPLETELY INNOCENT ... and claims the woman accusing the former MLB star of rape is nothing more than a lying publicity whore.

We spoke to Leila Knight -- who dated Canseco for more than 4 years -- and she tells us she's spoken with Canseco at length about the sexual assault accusations that have been made against him in Las Vegas.

"I've been talking to him all day ... it's obvious that it's a publicity stunt, I mean -- the girl's an aspiring actress," Knight says.

Knight also says Canseco is a "gentle person" who always tells the truth -- "If anything, he's too honest."

For his part, Canseco has denied any wrongdoing ... despite the fact he's named as a suspect in a sexual assault investigation stemming from an alleged incident on May 10.

An internationally-known MMA fighter ... claims a gel that is supposed to enhance sexual performance has ruined his ... claiming he now has a bum penis that can't ejaculate.

Waylon Lowe claims in a new lawsuit ... he bought a tube of Kama Sutra Pleasure Balm Prolonging Gel at a Philly sex shop -- which is supposed to desensitize the penis and enhance stamina.  He lathered the gel on his junk and then covered it with a Trojan Magnum latex condom and began having sex with his fiancee.

The sex didn't last long, because their baby started acting up in the next room.  While the fiancee tended to their daughter, Lowe claims he began experiencing excruciating pain in the penis.  He removed the condom and says he was horrified to see a significantly swelled penis.

Lowe says he ended up in the ER and has suffered "catastrophic and permanent damage" to his penis.  Among his many beefs:

-- permanent scarring and disfigurement
-- permanent loss of sensation
-- permanent loss of functioning
-- permanent nerve damage
-- loss of life's pleasures
-- inability to ejaculate

Lowe is suing for a minimum of $50k ... we're guessing he wants a lot more.

Lowe strongly insinuates in the lawsuit ... the damage was caused by placing the condom over the gel, despite the fact that the label gives users the green light to wrap it.

The Kama Sutra Company tells us the lawsuit is BS, claiming the product has worked safely without incident for 40 years.

Besides having tons of money, a ridiculously rich husband and a sick Malibu mansion, "Real Housewives of Beverly Hills" star Yolanda Foster also has a model child.

Yolanda supervised as her gorgeous 17-year-old professional catwalking daughter Gigi Hadid rocked a bikini and a pair of Roman gladiator sandals on a photo shoot in L.A. on Wednesday.

Fun fact: Yolanda is currently married to music mogul David Foster, but Gigi is her daughter with ex-husband Mohamed Hadid ... the celeb real estate contractor who just settled a huge lawsuit with Sylvester Stallone over alleged shoddy home renovations.

Foxy Brown is FURIOUS over reports she trashed Jay-Z ... telling TMZ she NEVER referred to Hova as a gonorrhea-infected "tranny chaser" ... and now she's threatening to sue.

Brown is referencing reports which say Foxy recently went to a baby shower and started dishing about Jay-Z's sex life to one of the guests -- saying he secretly engages in gay sex ... and that she lost her virginity to him when she was 15 and he was 27.

There's more ... including allegations of a robbery, sex tape and STDs.

But Foxy says the report is complete BS, telling TMZ ... "The atrociousness of this story sickened me to my stomach. Any and everyone involved will be contacted by my attorney."

Foxy says, "In all my years in the music industry, these are the most disgusting and disrespectful allegations I've ever experienced. This fictitious story ... with NO audio, visual or written interview, clearly was concocted with malicious intent."

"Jay has only been wonderful to me and my family, a great friend throughout all the years I've known him and we had nothing but great success as a team."

She continues, "Beyonce, his wife, has always been gracious and sweet to me ... I will NOT let any undercover hater create discord and disrespect my name and reputation."

"This disrespect will NOT be tolerated."
