(dailymail.co.uk ) - He may have avoided serious injury during his tour of duty in Afghanistan, but Prince Harry appears to have picked up his dangerous smoking habit after claiming to have quit.
The hell-raising royal - who reportedly started smoking at 14 and was on 20 a day at Eton - was seen puffing on a cigarette outside an aiport terminal.
And it's clear for the nicotine addict, old habits die hard.
Sgt. Dean Barnes, who spent time with the prince in Helmand province recalled: "He made out he was a non-smoker - then started cadging cigs. He still owes us a few."
Spending lots of time with girlfriend Chelsy, also a committed smoker, can't be helping his efforts to quit.
Harry, 23, was headed back from Cape Town, South Africa, after a holiday with his 22-year-old student girlfriend following his tour in Afghanistan.
While there, he was rarely seen without his favourite baseball cap on his head - at least during his off-duty moments.
And now he's back on civvy street, he hasn't forgotten that lucky headgear - he was pictured wearing it again on the streets of Cape Town last week.
The cap bears the American Stars and Stripes on the front, and the words "We Do Bad Things To Bad People" on the back - a slogan that prompted some debate about its suitability when he was fighting the Taliban.
But last week, as he strolled in the African sun with 22-year-old girlfriend Chelsy Davy, the ten weeks he spent on the front line in Helmand Province seemed a very long way away.
The couple - and Chelsy's parents - are on holiday at the home of wealthy wine-grower Gerrit Thomas Ferreira, a friend of the Davy family who owns the Tokara Wine Estate, just outside Cape Town.
At the mansion they have canoes, a houseboat and swimming pool at their disposal.
Last week, Chelsy - wearing a navy and white blouse, white mini-skirt and flip-flops - and Harry took a stroll through Cape Town.
Mr and Mrs Davy laughed and joked with the couple as they visited designer shops together.
On another excursion, Chelsy and the 23-year-old Prince tried their luck at a seafront pitch-and-putt golf course.
The pairs romance is clearly back on course, following rumours at the end of last year that the relationship was floundering.
However, Harry, a second lieutenant with the Blues and Royals, is expected to return to service with the regiment soon.
Meanwhile, military chiefs have expressed fears about the risks of deploying such a high-profile soldier in battle again.
