Rap star Kanye West has reportedly surprised Kim Kardashian West by buying her a $14 million apartment. Photo: Bang The 41-year-old rap star has agreed to pay the eye-watering sum of money for the spectacular apartment - which is designed by world-famous architect Norman Foster - in Miami's so-called billionaire beach bunker. A source told the New York Post newspaper's Page Six column: "Kanye saw the property during Art Basel in December and bought it as a Christmas present for Kim. It was a complete surprise for her." The 'Famous' rapper - who has kids North, five, Saint, three, and 11-month-old Chicago with Kim - has already agreed a deal for the luxury apartment and the sale is expected to close in January.

Meanwhile, Kris Jenner - Kim's mother - reportedly spent as much as $500,000 on her Christmas Eve party. The 62-year-old showbiz matriarch staged her annual December 24 bash at the Hidden Hills home of Kim and Kanye - and she spared no expense in making sure the family's 200 guests had a great time, with an insider saying the event is crucial to the family's "image" Photo: Instagram A source explained: "The party needs to be eye-popping because it sets the tone for their empire - it creates a fantasy world and makes people want to tune in, so $500,000 is nothing for them. "The grand spectacle of the party also helps sell Kylie [Jenner's] make-up, Kim's perfumes, and Khloe [Kardashian's} jeans. It's all about image." Rob Kardashian' imaginary friends Rob Kardashian has three imaginary friends, according to his sister Kim Kardashian West. The 'Keeping Up With The Kardashians' star's sister Kim Kardashian West revealed Rob would refer to his imaginary friends Pablo and Ronald from time to time, up until the last 12 months where he hasn't mentioned them since. In a bonus clip from Kim's appearance on Busy Philipps' E! talk show, 'Busy Tonight', she said: "My brother has - I don't know if he still does - but he had, for a really long time, two imaginary friends - Pablo and Ronald ... My brother literally has talked about these guys like, up until last year. He has one more, I can't remember his name." Meanwhile, Rob - who has two-year-old daughter Dream with his ex-partner Blac Chyna - has largely remained out of the public eye in the recent years and even shunned his family's E! reality show. In a court declaration, he shared: "I have not participated in the filming of any episodes since this summer when [Chyna] filed a request for a restraining order against me. Her request was widely publicised and I was scrutinised by the media. It has been an extraordinarily difficult time for me emotionally and I have no desire to continue participating in the reality show. I would like to maintain my privacy, try to recover from the emotional damage of the past several months, and explore other business ventures." Rob has also been battling with his ex-partner Blac Chyna in court over child support figures for their daughter Dream, two, but the pair have both agreed to stop the fight over the festive period and it is hoped they will be able to sort out a settlement privately. Sources said the duo were expected in court last week but it had mysteriously disappeared off the schedule. Kris Jenner paid 500k for festive party Kris Jenner's Christmas Eve party reportedly cost $500,000 - but was worth every penny. The 63-year-old reality star staged her annual December 24 bash at the Hidden Hills home of her daughter Kim Kardashian West and son-in-law Kanye West and spared no expense in making sure the family's 200 guests had a great time - and insiders insist the celebration, which will be seen on 'Keeping Up With the Kardashians', is worth every penny. The source explained: "'The party needs to be eye-popping because it sets the tone for their empire, it creates a fantasy world and makes people want to tune in so $500,000 is nothing for them. "The grand spectacle of the party also helps sell Kylie's makeup, Kim's perfumes, and Khloe's jeans. It's all about image." And despite the huge price tag, Kris reportedly bagged herself a bargain as party planner Mindy Weiss offered her a discount because they have worked together for so long. Mindy spent several months planning the party, which Kris requested had a Winter Wonderland theme, and Kanye - who has children North, five, Saint, three, and 11-month-old Chicago with Kim - was also heavily involved in the arrangements. The source told DailyMail.com: "The direction was a dreamy look with no red and green. Last year Kris went heavy on red and green in her home. But this year it was at Kim and Kanye's place, which is all white everywhere, so they wanted the decorations to be white too. "It was also said that Kanye wanted it to be especially over the top for his three kids. He wanted it to
