Kim Kardashian West was given a custom Monopoly game for her 40th birthday

Sharing the game with her Instagram followers this week, Kim said: "Oh my God, Simon just got me the coolest gift ever! It is Kimopoly!

"But look it, every last thing - that's my first apartment that I ever had, that is our first house that we filmed 'Keeping Up With The Kardashians' in, Momager tax, my first house that I bought, my dad's house, my best friend Allison's house, the hospital I was born in, SKIMS HQ, my dad's business. Hidden Hills, literally guys I'm dying.

"All of these are like memories! That's my high school, glam tax. Seriously I am dying. Literally every last thing means something.

"A weight, a TV, a camera, a hashtag, literally this is the cutest thing ever. With my nude colours, it's honestly perfect. Simon, I love you, and we're going to be playing Monopoly very soon."

Even the 'Chance' cards impressed, with references to Kim's daughter North West and her potential future legal career.

She added: "I have to read you these chance cards. This one says, 'Pay North's security detail, $15'.

"This one says 'Jeff Leatham's floral bills. How funny. 'Your Law Firm KKW Partners wins a huge case.' "

Meanwhile, Kim is reportedly set to fly some of her closest friends and relatives out to a private island to mark her birthday.

A source said: "All the guests know is when to be ready to be picked up for the flight, which will leave the Los Angeles area early next week.

"The destination is being kept strictly under wraps for privacy reasons, but that isn’t stopping everyone from speculating."

For safety, every guest has already been tested once for COVID-19 and will be retested again before they head abroad next week for the celebrations.
