Kristi Noem's husband is today revealed as a secret crossdresser who dons gigantic fake breasts and pink hotpants to chat with online fetish models.

While his wife has operated at the highest echelons of government, handling matters of national security in her recent role as secretary of homeland security, Bryon Noem, 56, has been dressing up and paying adult entertainers to talk dirty.

The Daily Mail has reviewed hundreds of messages involving three women from the 'bimbofication' scene – where porn performers transform themselves into real-life Barbie dolls by pumping colossal amounts of saline into their breasts.

Mr Noem has lavished praise on their surgically enhanced bodies, confessed his lust for 'huge, huge ridiculous boobs,' and even made indiscreet remarks about his 34-year marriage to Ms Noem, our investigation can exclusively disclose.

National Security experts consulted by the Daily Mail said his brazen behavior could have left the 54-year-old MAGA favorite, who oversaw ICE's aggressive crackdown until she was removed from her position on March 5, vulnerable to blackmail.

'If a media organization can find this out, you can assume with a high degree of confidence that a hostile intelligence service knows this as well,' warned former CIA officer Marc Polymeropoulos.

In a selfie shared with one of his online contacts, Mr Noem, an insurance mogul, can be seen squeezing into a flesh-colored crop-top and skintight pink shorts.  

The father of three appears to have stuffed two balloons inside his shirt to resemble breasts – positioning the knots to mimic nipples.

Another photo showed the rancher and businessman wearing figure-hugging green leggings and a white top stretched over two bulging orbs, with his face clearly visible in both images.

Mr Noem pouted playfully at the camera, seemingly unconcerned that his online activity could pose security implications for his wife's position at the heart of the Trump administration.

Texts and WhatsApp messages revealed Mr Noem was being repeatedly asked for money during the 14 months his wife led the nation's largest federal law enforcement agency.

He sent his secret roster of online acquaintances at least $25,000 (£19,000) via Cash App and PayPal but when the payments were delayed or failed to materialize the chats would quickly turn sour.

One of the women became so disgruntled she posted about his behavior on social media before later deleting it.

Jack Barsky, a former Soviet spy-turned-US counterintelligence asset, told the Mail the potential for blackmail was alarming.

'It's astounding that somebody whose spouse is at that level has that kind of bad judgment,' he said.

Mr Polymeropoulos, a CIA veteran of 26 years, agreed. 

'Damaging information like this can be a tantalizing lead for a hostile intelligence service.

'They approach the person and say, if you work with us we won't expose this, and if you don't, we will. That's espionage 101.'

When the Daily Mail reached Mr Noem by telephone he did not deny having explicit conversations or sharing photos of himself dressed as a woman.

It was also put to him that he had made indiscreet comments about his wife and could have endangered national security by exposing her to the threat of blackmail.

'Yeah, I made no comments like that, that would lead to that,' Mr Noem replied. 'I deny the second part of that.'

He then hung up.

'Mrs Noem is devastated,' a spokesman for the former secretary told the Mail.

'The family was blindsided by this. They ask for privacy and prayers at this time.'

Kristi and Bryon Noem met in high school, married in 1992, and raised daughters Kassidy, 31, and Kennedy, 29, and a son, Booker, 23.

Their marriage became the subject of intense speculation when the Daily Mail revealed her alleged years-long affair with close advisor Corey Lewandowski in a 2023 exposé.

Ms Noem, at that time the Republican hovernor of South Dakota, denied the fling and the Noems have since put up a united front.

Mr Noem supported his wife last month by sitting dutifully behind her at a congressional hearing scrutinizing her aggressive immigration enforcement tactics.

But the cameo backfired horribly when California Democrat Sydney Kamlager-Dove asked the outgoing DHS secretary: 'Have you had sexual relations with Corey Lewandowski?'

Ms Noem didn't issue an outright denial, instead snapping back: 'I am shocked that we're going down and peddling tabloid garbage in this committee.'

The vast trove of saucy texts, WhatsApp messages and images obtained by the Daily Mail reveals that clean-cut Mr Noem has his own share of secrets.

His fetish was '3000cc-plus boobs,' according to one of the models who communicated extensively with Mr Noem and agreed to describe their conversations to the Daily Mail.

That's a reference to custom-made XXL implants that can hold more than 3,000 cubic centimeters of saline per breast – far greater than surgeons typically recommend.

'It's called bimbofication. People who modify their body to look like a doll. The Barbie look,' she explained.

'His kink is for huge, huge ridiculous boobs.'

Mr Noem got in contact with a model using the pseudonym 'Jason Jackson', complimenting her 'amazing' curves and vowing to worship her like a 'goddess,' according to messages seen by the Mail.

In texts and audio calls, the pair shared everything from mundane daily chit-chat to spicy banter about her augmented chest.

'How are your boobs?' he asked her. 'Would you ever go bigger?'

The model sent him an array of topless selfies and lingerie shots.

'Jason' apparently felt relaxed enough to reciprocate with photos of himself wearing skimpy outfits and lopsided DIY breasts.

'You turn me into a girl,' he said. 'Should I put on leggings?'

A PayPal account belonging to 'Jason Jackson' sent the woman regular deposits, typically between $500-$1,000 (£380-£750).

She says he openly admitted to having a wife and family.

'He'd say, "I love my wife, I want to get better." Then he'd disappear, come back, and start again,' the woman added.

Over time, the models began to figure out the real identity of their shadowy benefactor.

A second woman told the Daily Mail she pocket-dialed Jason and was astonished to hear a voicemail greeting saying: 'Noem Insurance, leave a message.'

A quick Google search pulled up photos of Kristi and Bryon Noem.

'I was completely shocked. I said, "Why are you doing this?" I didn't think hot guys did this,' the woman said.

'He said he didn't care. I thought, you should care – your wife could lose everything she's ever worked for.'

The second woman had also read about Ms Noem's alleged affair with Mr Lewandowski, a longtime GOP operative who married 9/11 widow Alison Hardy in 2005 and has four children.

'I asked him about it and his response was, "I know. There's nothing I can do about it."'

Meanwhile, Ms Noem and GOP operative Lewandowski have continued to appear alongside each other publicly, with him even appearing at Ms Noem's side during her official trip to Guyana last week. 

Mr Noem appears to have curtailed his messaging around January of this year, just as his wife was overseeing the controversial deportation surge in Minneapolis, during which two US citizens were shot dead by ICE agents.

Trump removed her from the cabinet two months later amid bipartisan criticism of her clumsy efforts to label the victims, Renee Good and Alex Pretti, 'domestic terrorists'.

Insiders said the President was also furious after Noem told Congress he had approved a $220million (£165million) advertising campaign featuring her riding a horse at Mount Rushmore.

Markwayne Mullin, a conservative senator from Oklahoma, has since replaced her at the DHS while Noem became special envoy for the Shield of the Americas, an initiative created by Trump to strengthen international security in both North and South America.

The newly created role, widely seen as a soft landing for her, involves liaising with Latin American governments to fight drug cartels.

The Daily Mail ran the photos of Mr Noem through specialist software to check for any signs they had been generated by AI, but found no evidence of digital tampering - with consistent lighting across the face, chest, fabric and background.

The telltale signs of edited or fake pictures – such as visible seams, artifacts or background distortion – were also not detected.

The metadata suggests the pictures were taken in early 2025 on an iPhone set to Central Time, consistent with Mr Noem's South Dakota location.
