Prince Harry and Meghan have posted an adorable photograph of Archie in a touching tribute on Father’s day.

THE FAMOUS FRIEND: Serena Williams

Tennis icon Serena Williams has remained close friends with Meghan since the pair first met in 2010 at the Super Bowl in Miami, Florida.

Meghan previously wrote about their friendship on her lifestyle blog, The Tig, saying the pair had found an instant affection.

‘We hit it off immediately,’ she said. ‘Taking pictures, laughing through the flag football game we were both playing in, and chatting not about tennis or acting, but about all the good old fashioned girly stuff.’

The sportswoman, 37, was one of the pals involved in organising her baby shower in New York – and admitted that she’d pulled out all the stops to make it perfect for her pal.

She told Business of Fashion: ‘Planning something like that takes a lot of effort. I’m a perfectionist, so I’m like, “Let’s make it perfect”.‘

Serena was a guest at St George’s Chapel Windsor when Meghan married Prince Harry last May, and was one of the close friends invited to their more ‘intimate’ evening do for 200 friends.

AMAL CLOONEY

Human rights lawyer Amal Clooney, 41, and her husband George, 57, were in attendance at Prince Harry and Meghan’s wedding.

The mother of twins, who developed a friendship with the duchess during her transition to London, are connected through celebrity hair stylist Miguel Perez.

According to Elle, Meghan has been relying on Amal’s advice for coping with being in the public eye.

Amal and her husband are part of the well-heeled set of Berkshire-based celebrities who live close to Harry and Meghan’s new home at Frogmore Cottage.

Their sprawling home is just a 30-minute drive from Windsor and the couples are said to socialise regularly.

Harry and Meghan also spent a few days with the Clooneys at their 18th century Villa Oleandra in Lake Como in August 2018, relaxing by the pool and playing basketball.

THE MUTUAL FRIEND: Violet von Westenholz 

Violet von Westenholz, 33, is the daughter of former Olympic skier Baron Piers von Westenholz, who is a close personal friend of Harry’s father, the Prince of Wales.

She was also a childhood friend of Harry’s and met with Meghan while working as a press relations director for Ralph Lauren.

She was seen chatting with Meghan at Wimbeldon just days before her blind date with Prince Harry in July 2016, prompting speculation that she had set the couple up.

However, it’s since been revealed that the royal matchmaker was designer Misha Nonoo.

THE LA CONFIDANTE: Heather Dorak

Meghan’s close friend Heather Dorak was not at her baby shower – presumably because she had given birth to her own child only days earlier.

The duchess developed a close friendship with Heather during the time she spent attending her Pilates classes when she was an actress in LA.

Meghan has often gushed about being inspired by Heather who was a guest at her wedding to Harry.

THE SECOND FATHER: Mark Dyer

Mark Dyer has been noted as a ‘second father’ to Prince Harry throughout his upbringing and a mentor alongside the royal’s former nanny Tiggy Legge-Bourke.

Cheltenham ­College educated Dyer, known as Marko to friends, became a steadying big brother figure to the princes in the mid-Nineties when he worked as an equerry to the Prince of Wales for 18 months.

Prince Charles appointed Dyer to keep an eye on his sons, and he was brought in as a male counterpart to former royal nanny Tiggy Legge-Bourke.

During the first half term after Diana’s death, when the boys would have been with their mother, Prince Charles was committed to a five day visit to Africa.

He took Harry along and while the Prince carried out engagements, Harry went off on safari in Botswana, organised by Mark.

From then on he was a key guiding figure as Harry and William tried to come to terms with the loss of their mother.

After his spell as an employee to the Prince ended he remained a mentor to Harry.

In 2009 Mark founded the management company MDM Bars and Pubs and runs two pubs The Sand’s End and The Brown Cow, in south-west London which both became haunts of Prince Harry.

Mark’s six-year-old son Jasper, who is Prince Harry’s godson, was chosen as a page boy for the Duke and Duchess of Sussex’s wedding.

THE FAMILY MEMBER: Mike and Zara Tindall

Harry has shared a close bond with his cousin Zara Tindall since childhood.

Back when Zara had a tongue piercing and Harry was known for his wild nights out, the pair were known as the ‘fun’ royal rebels.

However, their friendship has endured now they are both settled down and in their 30s.

Indeed, it’s Harry who is said to be responsible for Zara’s happy marriage to Mike Tindall after introducing the pair at Manly Wharf Hotel in Sydney in 2003, during the Rugby World Cup.

Zara and Mike chose Prince Harry to be godfather to their second daughter, Lena, the Duke and Duchess of Sussex attended her christening in March at St Nicholas Church in Cherington, Gloucestershire.

THE FATHER OF HARRY’S GODCHILD: Jake Warren

Jake Warren and his wife Zoe attended the couple’s wedding, and their daughter Zalie – who is one of Prince Harry’s godchildren – was chosen to be a flower girl.

The godson of Princess Diana, Jake grew up alongside Prince Harry and has often been spotted with him at events including Ascot.

The Warren family are closely connected to the royals through horse-racing. Jake’s father John Warren is the Queen’s racing manager.

The father-and-son team run Highclere Stud in Newbury together.

THE CLOSE MATE: Nicholas Van Cutsem

Major Nicholas van Cutsem, a major with the Household Cavalry’s Life Guards, has been a friend of Harry and William’s since childhood.

He had an important role in the 2011 wedding when he escorted William and Kate along the procession route in London in a 1902 State Landau after their wedding at Westminster Abbey.

The Duke of Sussex chose three-year-old Florence, the daughter of Nicholas and his wife Alice Van Cutsem, as a flower girl for his wedding to Meghan.

Prince Harry, who has known Nicholas and Alice for several years, is Florence’s godfather.

THE BELOVED FORMER NANNY: Tiggy Pettifer

Tiggy Pettifer – better known as Tiggy Legge-Bourke – was famously Harry and William’s long-term nanny in their formative years.

A constant by the princes’ side while they were growing up, Tiggy has remained close to both the royals over the years, and met Meghan before they married.

The Duke of Sussex is godfather to Tiggy’s son Tom Pettifer, who was pictured with Tiggy at the royal wedding.

THE PREP SCHOOL FRIEND: Charlie Van Straubenzee

Charlie Van Straubenzee became a close friend to Prince Harry and Prince William during their time at Ludgrove Prep School in Berkshire, and was chosen to be an usher at Harry’s wedding.

The Duke and Duchess of Sussex attended Charlie’s wedding in Surrey just months after their own ceremony.

The Windsors and van Straubenzees have known each other since they were at Prep school together and are close friends.

Charlie’s older brother Thomas is Princess Charlotte’s godfather.

Harry has visited the family home in Cornwall almost every summer since he was a child.

THE SPEECH WRITER: Tom Inskip

Tom ‘Skippy’ Inskip and sister Victoria — ‘Tor’ to her friends — have known Princes William and Harry since childhood. The Inskips were regulars at Club H, the ‘nightclub’ William and Harry set up in the basement of Highgrove.

Tom attended Eton with Harry and co-owns a race horse with him called Usain Colt.

He later became known for being by Harry’s side whenever he got into scrapes, such as his infamous trip to Las Vegas in 2012, when the prince was photographed naked during a game of ‘strip billiards’.

But he’s been leading a more settled life since marrying flame-haired literary agent the Hon Lara Hughes-Young in Jamaica in 2017.

Harry and Meghan flew to Jamaica to attend Tom’s wedding, where the Prince was an usher.

Tom was a guest at the royal wedding in May 2018, and reportedly helped Prince William write a speech.
