CAD James Hewitt has finally admitted what Britain has known for years — he is a total s**t.

The smarmy ex-Guards officer makes the confession in a TV show about his attempt to sell love letters from Princess Diana for £10million.

He says drunkenly: “We’re doing the programme because I’m a complete s**t and we’re trying to make me less of a s**t.”

Hewitt, 45, also says he did Prince Charles a FAVOUR by having a five-year affair with Diana.

The creep claims: “I think Charles was probably grateful someone was looking after his wife when he was sh***ing Camilla Parker Bowles.”

In one sickening clip in the Channel 4 documentary to be shown next week a friend of Hewitt mimics his posh voice and says: “I’ve got some letters to sell from Princess Diana. Princess Diana was one hell of a ****.”

Hewitt laughs to the cameras and says: “It’s true. Don’t worry, we can edit that bit out.”

At one point he is filmed in the bath. He chuckles: “I’ve had to put extra bubbles in because I’m a big boy.”

He goes on: “I realised I was a bounder, realised from an early age, six or seven months, when I squeezed my nanny’s nipples.

“My mother said, ‘You absolute bounder you’.

“My father was always one for having an eye for the women — and his father.

“So I reckon it runs in the blood, so I’m not going to change and I should be grateful.”

And when asked how many women he had had, he says: “This week? This year?”

He goes on: “I never wanted to be a cad but I guess I am, so, if you’re handed a bunch of lemons make some lemon juice.”

Despite claiming he was trying to mend his ruined reputation, Hewitt remained a rat by allowing his lawyer and pal Michael Coleman to read extracts from the letters for the first time on TV.

They were sent to Hewitt in 1991 when he was serving in the first Gulf War against Iraq.

In one, Diana wrote: “Boy, oh boy, does the earth shake when I get a letter from my desert friend, screams of delight, tears, you name it. Demented female on the loose, that’s for sure.”

In another, dated January 17 — the day after the war began — the smitten princess wrote: “So, it’s started and I sit here glued to the TV and radio hoping you’re ok.

“I’m extremely worried and pray that the war will be over soon.

“Your letter was such a joy. Me and the boys think of you lots and pray for your return.” In yet another note, Diana joked: “So there are 30,000 ladies in the Gulf.

“That should keep you busy my friend. Variety is the essence, I’m told.”

She also referred to her younger brother Charles Spencer’s affair with cartoonist Sally Ann Lasson.

The princess wrote: “My brother is in trouble with a legover situation after he was married.” And she added: “I miss you terribly.”

Shameless Hewitt was followed by a film crew as he travelled to America looking for a buyer for the Diana letters.

His latest sick bid to cash in on the princess sparked uproar on both sides of the Atlantic. But the former Army officer defended his decision, saying: “They’re nice letters.

“She’s sadly dead and gone, it’s not going to do anyone any harm, particularly if it goes to a private collector.”

Last December, The Sun’s sister paper the News of the World caught Hewitt trying to sell the letters.

The ex-Life Guard had vowed he would never do such a thing. But by the time the paper uncovered the plot he had already rejected a £4million offer. And he tells the Channel 4 programme: “I’d like the letters to go for as much as they could possibly get. I don’t think it’s a particularly immoral course of action to take. I don’t think it’s immoral.”

Asked how he would feel if someone was going to sell his private letters, he says: “I’m not going to discuss it.”

He then becomes angry and cuts short the interview, adding: “I think there’s enough of this. I don’t want this to continue, I’ve had enough.”

Hewitt says of his romance with Diana: “It has meant momentous things. Knowing her for five years has changed my life forever and I just don’t like talking about it, I find it very difficult.”

Asked if Prince Charles knew about their relationship, he says quietly: “Yes. He would have been told by security forces and other people who make it their duty to know what other people are doing.”

Coleman, responsible for brokering any potential letters deal, is seen saying that selling them for £10million would rake in £8,000 a week in interest.

And he blasts: “Ninety-nine per cent of people would sell them. You can either work for a living or sell the letters. I know what I’d do.”

Coleman is shown hawking the letters at auction houses Sotheby’s and Christie’s in New York.

But both companies refuse to take them, because they do not want to upset the Royal Family.

Only small extracts of the letters could be read on TV because Hewitt did not own the copyright.

Referring to anger from Princes William and Harry at their sale, Hewitt said: “I respect them, I think they’re wonderful. I haven't seen them for an awfully long time.

“But I wouldn’t tell them what to do with their own private property and I don’t expect them to tell me either.”

Confronted with rumours that he is Prince Harry’s father, he says: “I’ve told them that he’s not, I just think it’s very sad for him.”

Throughout the documentary, Hewitt lives up to his playboy image by boasting that the number of lovers he has had exceeds the average number of runs the English cricket team gets in a season.

But one of his former girlfriends, Emma Stewardson, says: “Everybody wishes that he would just go away — the Royal Family, the whole population of the country, me, my family. For heaven’s sake shut up.

“He’s either an utter fruitcake or he’s playing very nasty games.”

Hewitt failed to sell the letters in the US. But the final word went to Coleman who revealed they had thought of offering them on an internet site.

He said: “We’ve considered putting them up for auction on ebay.”

Diana said of Hewitt during her infamous 1995 Panorama interview: “Yes, I adored him. Yes, I was in love with him. But I was very let down.”

But since she died in a 1997 Paris car crash — at the age of 36 — Hewitt has made a fortune out of their affair.

He received an estimated six-figure sum for co-operating with author Anna Pasternak as she wrote Princess In Love.

And he got around £150,000 for various newspaper revelations about his relationship with the princess.

Hewitt was also paid some £40,000 for a photo shoot at his Devon home for a magazine.

His caddish antics have led him to be barred from his regimental headquarters.

His name was “entered on the gate” — a traditional way of shunning a former Guard for bringing discredit on the regiment.
