Seems Aaron Hernandez got jacked for his official jail I.D. card during his stint in the slammer -- 'cause it just surfaced on eBay ... TMZ Sports has learned.

Law enforcement sources tell us ... the item appears to be a legit identification card from Suffolk County Jail in Mass where Hernandez arrived in July 2014.

Starting bid -- $500.

As for the seller -- that person has not revealed his own identity ... but explained in the eBay post, "I was in jail with Arron Hernandes [sic] the for patriot super star.. I happen to com [sic] across his jail id."

Wonder how that happened?

We reached out to the Suffolk County Sheriff's Department -- but they're not saying jack squat about the situation.

With so much violence on reality TV, the chicks from "Rica Famosa Latina" have decided to get the upper hand -- by training in jiu jitsu at an MMA gym where Ronda Rousey gets down!!

It's no joke ... after the massive BRAWL at the premiere party last year (video below) Sandra Vidal and Victoria Del Rosal decided it was probably time to learn how to fight.

So, they hit up the famous Gracie Barra Burbank Monday for some real deal training in grappling ... since most reality show fights end up on the ground anyway.

FYI -- the gym is owned by ex-UFC fighter Alberto Crane ... and they don't mess around at this place.

We're told the ladies learned everything from punch defense to rear-naked chokes ... and their trainer Donny says they were "pretty good" for having no formal training.

Senoritas ... you've been warned.

Justin Bieber will be arrested if he dares to travel to Argentina, because a Buenos Aires judge has put the word out to police ... Bieber's a wanted man.

You may recall, a photog claimed Bieber ordered his bodyguards to attack him in November 2013, as the singer left a club. Bieber had been ordered to appear for questioning in November but apparently that never happened.

The judge who issued the most recent order on April 8 said, "I consider it pertinent to order the immediate detention of the accused."

Bieber's reps have said the case has been resolved, but apparently the judge doesn't see it that way.

The Big Sean/Justin Bieber feud is over before it even started ... or more accurately ... it never existed in the first place.

A rep for Big Sean tells TMZ the tweet going around in which Sean threatened Bieber for laying hands on Ariana Grande during a concert ... is a fake.

We're told Justin and Sean are good friends ... and that he and Ariana are just fine.

Another tweet of Sean's -- "so many times in my life I wish I could of been at 2 places at once" -- also sounded like it was about Bieber ... but we're told it had nothing to do with JB, and Sean just misses friends and family while on the road.

Don't all guys sit around the house like this???

Here's soccer superstar Cristiano Ronaldo ... striking a very spread eagle-ish pose to promote his new CR7 underwear line.

According to the press release, Ronaldo's new undies are supposed to be super soft thanks to "superfine microfiber" material.

Here's international supermodel Irina Shayk ... showing off her INSANE physique during a beach trip in Cancun, Mexico.

The 29-year-old's bikini top battled heroically to stay in position as Irina splashed around in the surf ... and while there were several close calls ... it ultimately emerged victorious.

Of course, Shayk recently broke things off with her longtime soccer superstar boyfriend Cristiano Ronaldo -- who's gotta be kicking himself right now ... or banging someone else.

9:45 AM PT -- Big Sean just weighed in again, and tells TMZ ... someone, other than Bieber, pulled a fast one on him.

Justin Bieber got a little handsy with Ariana Grande during a performance Wednesday night ... much to the dismay of her boyfriend Big Sean, who went on Twitter and threatened him.

Bieber made a surprise appearance at Grande's concert at the Forum in L.A. Wednesday, where the two performed "As Long As You Love Me." Toward the end of the song, Justin calls her over, tells her to stand in front of him ... and throws his arms around her.

It's pretty apparent ... Ariana's not having it and she quickly disentangles.

But apparently not quick enough for Big Sean, who was in Canada -- and caught wind of Bieber's antics through social media. He tweeted (and later deleted), "This kid is about to learn not to touch my girl like that. Beliebe that."

Jennifer Lopez and her NOT boyfriend are enjoying a NOT vacation in Mexico for his NOT birthday.

You get our drift, right? It IS Casper Smart's 28th birthday, and he and JLo ARE on vacay with her kids -- yet during an interview this week ... Jennifer insisted she's single.

Casper did some jetskiing ... JLo's kids went horseback riding, and JLo followed them all around town. Check out the pics ... no kissing or canoodling, but they're definitely close.

As we reported ... sources connected to Jen and Casper tell us they never really broke up -- and a couple weeks ago they were kissing outside "American Idol."

But yeah, like she says ... they're not dating.

Shocking moment in the Aaron Hernandez case -- the ex-NFL star's lawyer just suggested that Aaron was a WITNESS in the Odin Lloyd murder ... and the killer was someone he knew.

Hernandez's attorney just wrapped up his closing statements -- and while once again denying Aaron pulled the trigger ... told the court that Hernandez was merely a witness.

"He was a 23-year-old kid who witnessed something, a shocking killing, committed by someone he knew," Aaron's lawyer said.

The hammered guy who nailed Jennifer Lopez's brand spanking new Rolls-Royce is getting off easy -- despite a BAC nearly twice the legal limit -- he won't do jail time.

Law enforcement sources tell TMZ ... Robert John Reitz plead no contest to one count of DUI, and an L.A County judge sentenced him to 3 years probation and ordered him to complete a 3 month alcohol program. That's it.

Reitz plowed into JLo and Leah Remini last September on PCH ... then fled the scene. He later blew a .15.

JLo did get $25k in restitution ... which probably covers a cracked taillight on a Rolls.

Jessica Alba continued to do what she does best Thursday in St. Barts ... rock a bikini better than pretty much anyone.

Selena's murder 20 years ago today was every bit as big as the death of John Lennon, Elvis Presley and the assassination of John F. Kennedy ... so claims the estate of the former Tejano music queen.

Selena's estate claims in new legal docs her record label is hoarding huge amounts of money that should go to Selena's loved ones. In fact, the estate claims Selena actually became way more popular in death than life.

With 60 million albums sold, the estate is livid that UMG is not honoring the deal -- that the estate gets 50% of net profits for things like ringtones, downloads and other stuff.

Selena was gunned down by the former president of her fan club on March 31, 1995.

Jose Canseco's model daughter isn't a model citizen ... she just got busted for DUI.

Law enforcement sources tell TMZ ... Josie Canseco was pulled over around 1 AM on the corner of La Cienega and Melrose (right in the heart of Hollywood) after cops observed her hitting a curb.

We're told the 18-year-old -- who's appeared on mom, Jessica's reality show -- was given field sobriety tests, which she didn't pass, and was subsequently arrested. But our sources say cops didn't think Canseco was under the influence of alcohol ... they believe it was drugs.

Canseco was booked around 6:15 AM and, as of this posting, is still locked up on $15,000 bail.

We've reached out to Josie's rep, and also Jose ... no word back yet.

New England Patriots owner Robert Kraft just took the stand in the Aaron Hernandez murder trial -- and told the court his former tight end was adamant he did NOT kill Odin Lloyd.

Kraft says he spoke with Hernandez at the Patriots facility two days after Lloyd was killed -- and asked Aaron if he had anything to do with the killing.

"He said he was innocent," Kraft told the court.

At the end of the conversation, Kraft says Aaron hugged and kissed him.

Kraft says Hernandez denied having any involvement -- and said he was at a nightclub at the time Lloyd was murdered.

Aaron Hernandez essentially had a hall pass to cheat on his fiancée whenever he pleased ... because she says she knew all about it ... but decided to look the other way.

Shayanna Jenkins testified for the second day at Hernandez's murder trial where he stands accused of killing Odin Lloyd back in 2013.

Jenkins testified that she broke things off with Hernandez after she found evidence that he was banging other chicks on his cell phone. But Jenkins says she got back with Hernandez anyway because their bond was too strong.

After they reconciled, Jenkins says she decided to "compromise on his behavior, and that included infidelity and everything that came along with that."

Jennifer Lopez and Casper Smart did NOT get back together, because we found out they were never really apart.

Sources close to the couple tell us ... the break-up they announced in June was a business move. Multiple sources say in the spring they did stop seeing each other, but only for a few weeks.

We're told JLo was hawking her movie, "Boy Next Door," and honchos on the film felt creating a buzz that she was hooking up with co-star Ryan Guzman would help sell tickets. It's hard to do that when you're not single.

But the decision wasn't one-sided. We're told Casper was up to the same thing because he was shooting "Street," a UFC fighter movie where he buffed up. Again, he was more appealing single.

It all makes sense now. Two months after they revealed their break-up, a photog got shots of them in a convertible BMW. When JLo saw the photog, Casper put the top up and she slumped down in the passenger seat, out of sight.

Then in December, a dog at Jennifer's house bit a neighbor. Turns out it was Casper's dog that did the deed and he came running out of the house in his pajama bottoms after the attack.

In February, Casper went to a GQ event, and when he left he walked down the block and jumped in a car JLo was driving, avoiding photogs. A few minutes later a photog saw them walk into a restaurant together. When they saw the guy they hightailed it inside.

And then they got bolder, dancing together at a Big Sean concert at the House of Blues in WeHo.

Case closed.
