Fat Joe has just turned himself in to prison to serve his 4 month sentence for tax evasion.

The rapper -- real name Joseph Cartagena -- is officially in custody at the Federal Detention Center in Miami.

As TMZ previously reported, Joe pled guilty back in December to stiffing Uncle Sam on a boatload of taxes for the years 2007 and 2008 ... more than $1 million total.

He originally faced up to two years in the slammer for the crime -- but was ultimately sentenced to just 4 months and a $15,000 fine, plus one-year supervised release.

Spanish radio superstar Piolin has filed a lawsuit against 6 former co-workers ... claiming they were all part of a diabolical plot to shake him down for roughly $5 mil by threatening to go public with false allegations of sexual harassment, TMZ has learned.

Piolin -- real name Eddie Sotelo -- claims 6 former Univision employees contacted him last week and offered to "seal their lips" if he forked over $4.9 million in hush money.

In his lawsuit, filed today in L.A. County Superior Court, Piolin claims the six had threatened to come forward with allegations that mirrored those of another Univision employee who recently accused the radio star of sexual harassment and workplace misconduct. Piolin claims the accusers "have attempted a naked money grab, but have sorely underestimated their target."

As we previously reported, the other Univision employee is Alberto "Beto" Cortez -- who complained to Univision honchos that Piolin would grab his ass and genitals when he would arrive to the workplace. He claims Piolin would also berate him with homophobic slurs.

Piolin adamantly denied Beto's allegations -- claiming Beto concocted the whole story in a pathetic attempt at a shakedown.

As for Piolin's new accusers -- the radio star acknowledges he made outrageous and sarcastic comments on the air ... but says, "Everyone knew this 'horseplay' was all in good fun." Piolin also believes his zany antics were part of why his radio show was a success.

Here's Tom Brady casually paddling away in a kayak over the weekend ... and GIVING ALL OF BOSTON A FRIGGIN' HEART ATTACK!!!

Before you accuse us of sensationalizing the situation, consider this fact -- back in 2009, Brady had to be RESCUED from the Charles River after falling out of his Kayak while goofing around with some friends.

After the rescue, Brady thanked the woman who fished him out of the water ... telling her, "You saved my life."

Despite the risks -- and with NFL opening day less than 2 weeks away -- Brady got back into the Charles River with his wife Gisele and son Ben on Saturday.

Fortunately, everyone emerged from the water healthy and happy.

Meanwhile, it's the Jets who seem to be drowning these days ...

Selena Gomez walked the red carpet at the MTV VMAs moments ago ... sadly half her dress got lost on the way over.

No one bothered to look for it.

Taylor Swift + Jennifer Lopez's ass + songs from 2002 = CONCERT GOLD.

It all went down at Taylor's concert in L.A. Saturday night. The pretty-straight-laced singer has been inviting a slew of guests to perform with her on tour: Sara Bareilles, Ellie Goulding, Tegan and Sara ... acts that fit the Taylor mold.

But Saturday she threw that out the window and brought out Jennifer Lopez instead to sing "Jenny From the Block" as a duet ... and even tried to rock some fly girl moves.

Good news, single heterosexual men and/or lesbians: Eva Longoria (the sexiest 38-year-old woman on Earth) is now officially single.

Sources tell TMZ, the former "Desperate Housewives" star split from boyfriend Ernesto Arguello this week after dating for roughly 4 months.

The two met while Longoria was producing her dating show "Ready for Love." Ernesto was a bachelor on the program, but after the show went off the air, Eva decided to take Ernesto for herself.

Eva and Ernesto were spotted canoodling in Spain as recently as two weeks ago (above), but once they got back to L.A., we're told they decided their busy lifestyles just didn't mesh.

Eva spends most of her time in L.A., and Ernesto is situated primarily in Miami, so they decided it would be better to split. But some sources aren't convinced it's completely over -- as one source put it, "They're just on hold right now."

Translation: if you want to scoop Eva up, you better act fast.

11:03 AM PT -- The prosecutor just announced the indictment returned against Hernandez on multiple charges, including murder, carrying a firearm, possession of a firearm, possession of a high-capacity firearm or feeding device, and 2 counts of possession of ammunition.

As he sat down, Hernandez mouthed the words "I love you" to family members in court.

Another hearing has been set for next Friday.

NFL star Aaron Hernandez has just been indicted on a 1st degree murder charge in the death of 27-year-old semi-pro football player Odin Lloyd -- and he's due in court any moment to face his stark new reality.

Hernandez was originally expected in court today for a probable cause hearing -- where prosecutors would have presented evidence that a) a crime was committed, and b) that Hernandez committed the crime.

But a grand jury has already returned an indictment, meaning prosecutors won't have to present additional evidence to justify a trial.

Translation: the probable cause hearing is now pretty much a formality ... but we may still hear from Hernandez' lawyer.

Someone's been sleeping in Jennifer Lopez's pool house, and it ain't Goldilocks -- cops arrested an alleged stalker who somehow managed to live in the pool house of her massive Hamptons mansion ... for several days ... without getting noticed.

According to Southampton police, 49-year-old John M. Dubis basically moved in to J.Lo's $10 million pad sometime in early August.

He reportedly walked around the estate freely, hanging out openly in view of neighbors... and even posted Facebook photos of himself all over the grounds, such as the one below -- before police finally busted him on Aug. 8.

And how's this for weird ... two days before his arrest, Dubis dropped by a nearby menswear store and purchased a plaid overcoat.

Jennifer was not home, but the shocking part is security guards were patrolling the property.

Of course, you have to remember the 8,500 sq. foot home sits on 3 acres -- and it's a decent hike out to the pool house from the main quarters.

Dubis was booked for burglary, stalking, and criminal contempt. He pled not guilty, and is currently sitting in jail in lieu of $100,000 bail. The judge has ordered a mental evaluation for Dubis.

It's a brawl of the Brazilian models!

Ana Beatriz Barros (31) strolled on the beach in Greece with a sexy striped bikini and wild sunglasses yesterday (left) -- while Alessandra Ambrosio (32) wore an even stripier bikini and even wilder sunglasses along side her (right).

Romeo's idea of the perfect 24th birthday gift involves Justin Bieber's on-again/off-again gf Selena Gomez!

What bro code??!!

Hillary Clinton is already building a pretty impressive list of celebrity backers ... 'cause Eva Longoria just told us HC can count on her support if/when she decides to run for President in 2016.

It ain't too surprising, considering Longoria is a die-hard democrat who even gave a speech at the 2012 Democratic National Convention.

Eva joins a ton of Hollywood stars who are already on-board the Clinton Express ... including Lionel Richie, Chris Rock and Barbra Streisand.

Of course, Hillary hasn't officially announced her plans yet ... but at this point, does she even have to?

MMA legend Tito Ortiz is no stranger to bad breakups ... and tells TMZ he's moved on from the UFC because he knows Dana White ain't lookin' to bury the hatchet anytime soon.

Dana and Tito famously trashed each other following Tito's last UFC fight back in 2012 ... and Ortiz has since struck a deal with Bellator, a rival MMA organization.

In fact, Ortiz is set to fight fellow UFC-defector Rampage Jackson under the Bellator banner in November.

But, when we asked Tito if there was any chance at patching things up with his former boss and returning to the UFC ... Tito simply explained, "Nah, Dana holds grudges."

It ain't the first time Tito and Dana have gone after each other -- they also tore each other apart back in 2008 ... and Tito left the UFC ... only to return one year later.

Melanie Griffith brought a very interesting date to the premiere of her movie "Dark Tourist" this week -- her ex-husband Steven Bauer ... a guy she's BARELY been seen in public with since they divorced more than 20 years ago, TMZ has learned.

Griffith and Bauer (who famously starred in "Scarface" back in 1983) were all over each other on the red carpet ... which raised eyebrows considering Melanie's current husband, Antonio Banderas, was no where to be found.

According to our crack research team, the last time M & S were photographed on a red carpet together was back 1985 ... back when Ronald Reagan was President.

There have been rumors that Melanie and Antonio have been going through a rough patch ... which makes her decision to walk her ex down the red carpet even more curious.

Sources close to the couple tell TMZ ... despite divorcing in 1987, Melanie and Steven have remained close over the years and have worked together to co-parent their son Alexander Bauer, who also attended the premiere.

We reached out to Melanie's people -- but didn't hear anything back.

Jennifer Lopez must sure think Casper Smart is cute, because upstairs there's a vacancy -- he just ruined her big announcement that she's returning to "American Idol."

Smart was promoting his new show -- yes, anyone can -- when he was asked if his GF was coming back to the struggling show. He dug deep and said, "Yes."

Apparently Casper thought the cat was already out of the bag.

Miguel -- the guy behind the smash hit "Adorn" and "#Beautiful" with Mariah Carey -- was arrested for driving drunk in L.A. early this morning ... TMZ has learned.

Law enforcement sources tell us ... California Highway Patrol officers initially flagged the 27-year-old singer's 2013 BMW X6 for speeding and tinted windows next to an L.A. freeway around 2:15 AM.

During the stop, officers noticed the smell of booze ... and performed various field sobriety tests, which he flunked.

Miguel -- full name Miguel Jontel Pimentel -- also took a breathalyzer and blew a .10 and .11 ... which is over the .08 legal limit in CA.

Miguel was then arrested for DUI and hauled to a nearby station where he was booked ... and released a few hours later on $5,000 bail.

According to his booking sheet, Miguel is 5'7" and 140 pounds.

He's scheduled to appear in court in September.

So far, no word from Miguel's camp.

Alex Rodriguez not only feels the MLB is singling him out ... he feels "persecuted" in the PED scandal -- and plans to SUE if the league doesn't COMPLETELY recant ... TMZ has learned.

Sources directly connected to A-Rod tell us he's prepared to march into Federal court next month ... unless the 211-game suspension the MLB slapped him with last week isn't entirely lifted.

The reason for A-Rod's bold demand -- A-Rod sources familiar with the investigation tell us Alex hasn't tested positive and never "knowingly" used PEDs since 2003 ... the last season he admitted using 'roids. Our sources say A-Rod has been drug tested 11 times between 2011 and the present ... and all of the results were negative.

Our sources fume it's "absurd" Ryan Braun -- who reportedly tested positive in 2011 and then lied about it -- was only benched for the duration of this season. They say it proves MLB's investigation of A-Rod and the Biogenesis Clinic has been "abusive and borderline illegal."

As for rumors A-Rod impeded baseball's PED investigation -- our sources say the league has "no proof" the Yankees slugger did any such thing, and further claim MLB is the one that has harassed and intimidated witnesses.

According to our sources, Alex will sue for various things, including a violation of the Collective Bargaining Agreement between the players' union and the league.

So, from 211 games to nothing ... or else.

Pretty big cojones for a guy accused of using steroids.
