Sean Smith - Kim Kardashian

Kim always favours the house sushi roll when she visits Shibuya. In actual fact, they had no need to stop off at all, because they employ a full-time chef. My own chef was not so absorbed in news of the Kardashians. He was extremely interested in Manchester United, however, and dreams of the day when Wayne Rooney pops in for a sashimi snack.

In and around the exclusive little shops, ice cream parlours and health food stores, you are far more likely to see Kim’s younger half-sisters, Kendall and Kylie Jenner, who, as teenagers do, prefer to hang out in the mall with their friends than in the fur-lined prison of their gated community.

Round the corner for coffee at the Blue Table deli, a young woman, who was working in Calabasas while she waited for her break as a singer, told me that she had seen Scott Disick the day before. The long-standing boyfriend of Kim’s sister Kourtney, and the father of her children, has become a well-known face from his regular appearances on the TV show. ‘What does he actually do?’ asked my companion. I had to admit I had no idea and made a mental note to find out.

Having celebrities pop in does wonders for local trade. A few hundred yards away, in yet another shopping centre, El Camino, is a ‘homey café for health-conscious bites’ called Health Nut, which has become celebrated as the place where the Kardashian girls buy the salads they are always munching on TV. I pop in to grab a takeaway of Kim’s favourite salad, whatever that might be.

‘No problem,’ said the man at the counter, bashing my order into the till and taking the money.

‘What’s in it?’ I asked.

‘No idea,’ he responded smilingly. ‘I just hit a button marked “Kardashian”.’

It turns out to be a pretty dull chicken salad with a pleasant tangy dressing – nothing the chef couldn’t run up in five minutes at home.

For a while, the Kardashians had a major rival as the most famous faces in the neighbourhood when Justin Bieber bought a house in a gated Calabasas community called The Oaks for $6.5 million in 2012. These days it’s a Kardashian enclave. Justin tired of life in the suburbs after two years and sold his five-bedroom mansion, complete with pool, hot tub, movie theatre and skateboard ramp, at a $1 million profit to Kim’s sister Khloé. She can easily walk round to see their elder sister Kourtney, who also lives there.

Khloé’s mansion is relatively ordinary compared to the extraordinary palatial luxury enjoyed by Drake. He is one of the biggest stars in the US, although he has yet to cross the Atlantic with similar success. His best-known British hit was as the featured artist on Rihanna’s number one ‘What’s My Name?’.

He lives in an outrageously opulent home in Hidden Hills, which was originally on the market for $27 million in 2009, but he was able to pick it up for the knockdown price of $8 million after the property market collapsed. It has a cinema, wine cellar, stables, volleyball court, Olympic-sized pool, stables, wet-room bar and so on. Drake once sang on a number called ‘Versace’ by the hip-hop group Migos: ‘This is a gated community, please get the fuck off the property.’ He may rap the language of the street, but I don’t suppose he wants to live anywhere near one.

Hidden Hills is the gated community that attracted Kris and Bruce Jenner when they were looking to move from Beverly Hills while Kim and her siblings were still at school. Kris was first introduced to the neighbourhood by a friend after her marriage to Kim’s father, Robert Kardashian, had collapsed.

There’s rumoured to be more money in Hidden Hills than in Bel Air. Kim and Kanye have now bought an estate there with an estimated value of $20 million. I heard they are going to turn it into a palace and it’s going to make Drake’s property seem like a terrace.

It’s supremely ironic that gated communities don’t just keep the public out, they fence the residents in. You can’t get past the guards without an appointment or, it seems, an E! Entertainment Television identification badge. At least for the famous people who live here, it means the paparazzi aren’t looking over the garden fence.

Hidden Hills has a number of entrances and exits, so the photographers split up and wait at each one. Kim will leave eventually, but they won’t know in advance which exit she is going to use. When she is spotted, the photographer stationed at that particular gate texts everyone else that she is on the move. By clubbing together in this way, they ensure that they all have the opportunity to get a picture. It is reminiscent of the days when squadrons of paparazzi used to hang around outside Kensington Palace in the hope that Princess Diana would go out. A Kim picture guarantees a sale in much the same way as one of the adored royal icon did.

I popped into a hotel in Calabasas to ask for some directions and told the receptionist, probably a resting actress, that I was writing a book about Kim Kardashian. She volunteered, ‘I don’t really like her. I don’t see what her point is.’ It reminded me of local hostility against Britney Spears when I visited McComb, Mississippi, where she was born. Perhaps it’s the way people always feel about the most famous face in their midst.

I enjoyed my day in Calabasas, but I needed to beat the traffic on the freeway to return to downtown Los Angeles and civilisation. Before I left, there was time to ask an elegant woman shopping for clothes in a boutique very similar to DASH what she thought of the Kardashians: ‘You don’t get anywhere in that family without a vagina. Bruce has realised that …’

Kim Kardashian West demonstrated to the world the global power of her celebrity when she arrived at the Armenian Memorial Complex in that obscure country’s capital of Yerevan in April 2015. The pictures of her, solemnly carrying a bunch of bright red tulips that matched the colour of her dazzling jumpsuit, went round the world.

After she had laid the tribute at the eternal flame, bedlam broke out as TV cameramen and photographers – and the public brandishing phones – battled for pictures of Kim and her family. It had been the same story ever since she had touched down in Mother Armenia, as she calls the land of her ancestors.

‘Armenia, we are here!!!!!’ She posted to her then 30 million Instagram followers when she arrived. ‘We are so grateful to be here and start this journey of a lifetime. Thank you to everyone who greeted us. I can’t wait to explore our country and have some yummy food!’

On the flight from Los Angeles International Airport (LAX), Kim had slept completely hidden from prying eyes by a blanket. She always does this on planes so nobody can snap an unglamorous shot of her snoring with her mouth open. They flew the last part of their journey economy class, much to the amazement of other passengers.

When she arrived, she appeared completely refreshed, in ripped white jeans and a tight white top, although she hid her eyes behind a huge pair of sunglasses, in case the ravages of jet lag had caught her before her make-up artist, who always travels with her, could step in.

The visit saw Kim, and her younger sister Khloé, give an object lesson in how to combine glamour with tasteful respect. For their audience with the prime minister, they wore figure-hugging outfits that showed off all their curves. Kim chose beige and combined it with killer heels. Yet for their trip to the sacred Geghard Monastery, a World Heritage Site, she chose understated black.

Kanye West was on hand to secure his wife’s veil affectionately, although her wardrobe assistant took over to make the necessary adjustments for the perfect picture. Arguably, Kim has never looked lovelier than in this respectful homage to the country’s tradition. She looked very Armenian, with her coal-black eyes, long black hair and curvaceous silhouette.
