Gordon Ramsay had the guts to enter the grueling Ironman World Championship in Hawaii, but he ended up losing those guts ... on the side of a road.

Chef Ramsay had to drop out of the legendary race, but not before completing the 2.4 mile ocean swim. He moved on to the 122 mile bike ride, and that's when he started blowing chunks.

He tried to persevere through the final marathon leg, but went down with dehydration ... which prevented him from finishing. Medics had to come to his aid.

Ramsay's finished the race before ... in 2013 and it took him 14 hours. He says he'll be back next year.

Well this sucks ... the Dodgers just announced legendary broadcaster Vin Scully will miss working the playoffs after undergoing a medical procedure Thursday morning.

The Dodgers wouldn't say what the procedure was -- but insist the 87-year-old Hall of Famer is resting comfortably.

Scully made the decision to sit out the post-season on the advice of his doctors.

Still, the Dodgers insist Scully WILL return to the broadcasting booth next year for his 67th season with the team.

There's a difference between being sore over someone ... and GIVING SORES TO SOMEONE ... so says Gilbert Arenas who's suing his baby mama for claiming he gave her STDs.

The ex-NBA superstar has filed a lawsuit against Laura Govan -- claiming she concocted a diabolical scheme to humiliate him on a global scale by making everyone think he's rotten in the genitals, even though she knows he's not.

According to the docs, obtained by TMZ Sports, Arenas claims Govan got super bitter when he dumped her ... so she decided to write up an email to him chock full of nasty allegations and then leak it to various gossip websites knowing they would run it.

In the email, Arenas claims Govan wrote, "When I left you it was because I couldn't take the STDs."

Gilbert is adamant in his lawsuit the accusation is FALSE -- and "Govan knew it to be false when it was made."

The family of 13-year-old YouTube star Caleb Logan Bratayley says the boy died from an undetected medical condition.

No other details were given, except to say the family will have more definitive answers soon. It's unclear how much the family has been told, but it appears they know generally what triggered Caleb's death.

Caleb's memorial will be livestreamed on Periscope and Facebook.

Caleb passed away suddenly Thursday night in Maryland.

Kim Zolciak hasn't danced her final dance on "Dancing with the Stars."

We're told the folks at 'DWTS' want Kim back for the season finale next month. The plan is to have her dance in several dances on the final show and all she needs is a green light from her doctor.

We're told Kim's on board, despite being kicked off the show after suffering a mini-stroke that unearthed a heart condition. She's not back to 100%, but she already made it out of the house Sunday to watch husband Kroy play in the Falcons game.

Zolciak was at the bottom of the barrel on the show before her medical emergency. At least one person's rooting for her.

James Caan wasted no time ... less than 48 hours after he went to an emergency room, he was back at work, and smiling with his co-star Louis Gossett Jr.

TMZ broke the story ... the 75-year-old showed up to a Toronto hospital Tuesday night for a mild chest infection. He was treated and released, but we were told he'd be unable to return to set for a few days. No rest for the wicked.

Caan and LGJ are filming the family comedy "From Here to Infirmity."

Sweet irony.

The folks at Tinder and Grindr are attacking an AIDS org that is warning people they can get STDs by using the apps.

The AIDS Healthcare Foundation (AHF) posted a billboard in West Hollywood, telegraphing a warning -- you can get chlamydia by hooking up on Tinder and gonorrhea on Grindr.

Tinder has responded, courtesy of its lawyer who fired off a cease and desist order, obtained by TMZ. The letter says, "Tinder cannot tolerate AHF's exploitation of these false, unsupported statements." Tinder is demanding the billboards be removed immediately.

As for Grindr, it cut off AHF paid advertising for free STD testing from its app.

Kim Zolciak's mini-stroke was far more serious than anyone thought ... we've learned she had a heart procedure following the TIA and could have died.

As we reported, Kim had the mini-stroke in Atlanta, hours after appearing on "Dancing with the Stars." She had lost feeling on one side and her ability to speak, but it was only temporary.

Kim has told friends that doctors thought she could be released almost immediately, but a test revealed there was a more serious, underlying heart issue. Doctors kept her in the hospital and she told friends the docs performed a procedure Friday. We do not know the nature of the problem or what doctors did to correct it.

We're told Kim would never have known about the heart issue had she not gone into the hospital for the TIA. And doctors told Kim if the heart problem were left untreated, it could have become life-threatening.

Blake Shelton found a silver lining in his divorce from his country star wife Miranda Lambert ... it did wonders for his waist!

The 'Voice' star was chatting Wednesday with Blair Garner on the "America's Morning Show" when his dramatic weight loss became a topic of conversation.

Shelton says he didn't actively diet or hit the gym ... it's all about the stress of getting unhitched.

So more than half of people who get married should be real thin, right?

Kim and Khloe Kardashian, along with mama Kris Jenner, took a trip to San Diego Tuesday to get tested to see if they carried a genetic cancerous gene.

The women, accompanied by Dr. Paul Nassif from "Botched," went to Pathway Genomics, a company that tests for BRCA1 ... a gene mutation that causes a high likelihood of breast and ovarian cancer.

Angelina Jolie famously had preventive surgery after she tested positive. They were also tested for heart disease and diabetes.

The patriarch of Kim's family -- Robert Kardashian -- died of cancer at 59.

7-fingered bench press? No problem.

After critics said Jason Pierre Paul's disfigured hand would be a huge hurdle when it comes to weight training, the NY Giants star hit the gym ... to prove he can still lift weights, despite missing digits.

JPP busted out a set of bench presses -- with a towel in his right hand to stabilize the bar.

It's the second time Jason's posted training footage -- in an effort to prove he can still be effective in the NFL after seriously damaging his hand in a fireworks accident.

You convinced?

Houston Texans running back Arian Foster says he went to counseling to deal with several off-the-field issues -- presumably surrounding his divorce -- but says it was one of the best decisions he ever made.

As we previously reported, Foster's wife filed for divorce back in July -- more than a year after Arian fathered a child with another woman.

Moments ago, Foster addressed the media ... and turned the spotlight on his personal life -- saying, "I've been through some of the most tough times personally this last year but emotionally I'm probably the happiest I've ever been in my life."

Foster admits at first, "I thought I was too cool to get counseling. I thought I was above that" ... but says, "The only reason I'm talking about it now is because I know a lot of people out there now feel like I used to to feel."

Sylvester Stallone knows the secret to defeating Floyd Mayweather Jr. … but it doesn’t have anything to do with his next opponent, Andre Berto.

Almost no one is giving Berto a chance to win the fight -- so we asked Sly if he thinks he's even got a puncher's chance to upset Money. Check it out ... Sly says there's a chance, but not a puncher's one.

Stallone also throws a playful jab at "Southpaw" star Jake Gyllenhaal's on the topic of big screen boxers. We'll give you one guess which actor/fighter he IS backing.

Janet Jackson has put her life on hold to take care of her dad while he recovers from 3 heart attacks, and she's the only member of the brood who made the trek to Brazil.

We're told Janet arrived in Brazil Tuesday to tend to her father, cancelling rehearsals for her upcoming tour. We're told Janet limited the access to ICU, where Joe was hooked up for nearly a week.

The good news ... Joe's now out of ICU and on the mend. He's eating solid foods and the goal is for him to regain enough strength so he can get on a plane and return to the U.S. for further treatment.

We're told La Toya and Jermaine were talking about flying over, but when Joe's condition improved they decided to wait until he came home.

If all goes well, Joe could return home as early as Monday.

Liam Neeson had fans worried when he was spotted over the weekend looking frail and gaunt ... but his rep says the "Taken" star is in good health.

The rep says the 63-year-old actor is "healthy as ever," despite his ghostly appearance in the pic. The rep adds Neeson changed his diet and started doing more exercise about a year ago and credits that for the weight loss.

Plus, the rep says ... it's just an unflattering pic.

Apparently one of Neeson's "particular skills" ... is not always taking a great photo.

Joe Jackson has reportedly suffered a stroke that left him at the very least temporarily blind.

Jackson family sources confirm to TMZ, Joe was admitted to the Albert Einstein Hospital in São Paulo after reportedly waking up Sunday feeling dizzy, with no vision.

Joe, who has diabetes, was in the city for his 87th birthday party that was being thrown for him.

These pics were taken hours before the reported stroke.
