Prince Harry has arrived in Jamaica to celebrate the wedding of one of his closest friends - and is bringing girlfriend Meghan Markle to introduce to his 'crew'.
The fifth in line to the throne flew out from Gatwick to Montego Bay on Wednesday and is staying at one of the most luxurious resorts on the coast.
His so-called wingman, Tom 'Skippy' Inskip, is to tie the knot with his flame-haired literary agent fiancee, the Hon Lara Hughes-Young, reports Daily Mail.
One fellow traveller said the prince sat in a "premium economy" seat on the Virgin Atlantic flight to Jamaica, and reported that an elderly woman was moved to make way for his security detail.
Miss Markle, 35, was due to fly into Montego Bay on private jet from her home in Toronto tonight, sources told the Mail, in time for the wedding ceremony on Friday.
Friends say the three-day event promises to be "the mother of all parties", with even local hero Usain Bolt rumoured to be making an appearance.
It will provide the perfect opportunity for the US-born actress to spend quality time with Harry's tightly-knit social circle.
"This the first time that she and Harry have socialised so openly as a couple and is a significant step up in their relationship," one source said.
"Make no mistake, he is heads over heels about her. This one could go all the way."
Ironically divorcee Miss Markle married her former husband, producer Trevor Engleson, in Jamaica in 2011.
The pair tied the knot at the Jamaica Inn in Ochos Rios after dating for seven years, but split just two years later.
Harry, 32, and "party animal" Mr Inskip, 30, have been friends since they were pupils at Eton together and are utterly inseparable.
When the prince disgraced himself playing naked pool in Las Vegas, Mr Inskip was by his side. And when the royal jumped into a nightclub swimming pool in Croatia fully clothed in 2011, his close friend was there with him too.
That same year the pair were spotted throwing snowballs at passers-by from a hotel balcony in the upmarket Swiss ski resort of Verbier.
Mr Inskip, who was once photographed driving a convertible sports car naked in the US, his modesty only preserved by the steering wheel, was also with Harry when he was seen inhaling "hippy crack", otherwise known as laughing gas, at a party in 2010.
Such is the closeness between the two, it is believed that Mr Inskip - whose father, Owen Inskip, was a field master of Prince Charles's favourite hunt, The Beaufort - has asked Harry to be his best man.
The groom and his bride-to-be (daughter of Lord St Helens) have hired out the super exclusive Round Hill Hotel and Villas, a private 110-acre plantation style resort first built as a colony of cottages for the rich, famous and glamorous of the 1950s.
