Jay Z has turned down the chance to be Kanye West's best man.
The 44-year-old rapper only agreed to the idea initially providing his family, including wife Beyonce and their two-year-old daughter Blue Ivy, wouldn't be filmed for Kim Kardashian's reality show.
Speaking to the Daily Star newspaper, an insider revealed: "Jay is Kanye's closest friend so he wants him to be best man.
"Jay agreed initially but had one condition - under no circumstances can there be any reality TV shows filming him, his wife, Beyonce or daughter Blue Ivy during the ceremony."
However, E! bosses - who run Kim Kardashian's reality show - are reportedly "desperate" to air the ceremony, meaning Jay Z may miss out on being best man.
The insider said: "Bosses at E! are desperate to get the nuptials on air, and will pay millions to make it happen."
It's also emerged that Kim Kardashian will get $1 million for every year she stays married to West.
The couple have signed a prenuptial agreement, in which Kanye has been very generous toward his future spouse.
A source told RadarOnline.com: "The entire process for the prenup for Kim and Kanye has been extremely easy, and relatively drama free.
"Kanye didn't even think the couple needed a prenup, and was ready to give Kim carte blanche to all of his financial assets. Yes, he loves Kim that much."
The source adds drawing up the document was much easier than the last time Kim, 33, married, to basketball player Kris Humphries, in 2011, a union which lasted just 72 days.
The source added: "There is a huge difference from Kim's prenup with Kris Humphries ... the preparation of their agreement went on for several months. It was long and tedious."
The agreement states Kim will get $1 million a year for as long as she stays married, with a cap at ten years. Should they divorce she would keep all gifts given to her by 'New Slaves' rapper Kanye.
The couple's still incomplete Bel Air mansion will also be in Kim's name, even though Kanye has paid for the majority of it, and she will also benefit from one of Kanye's life insurance policies, valued at $20m, even in the event of a divorce.
According to estimates Kanye is worth $100m, while Kim - who was also married to Damon Thomas from 2000 to 2004 - has a personal fortune of around $40m from her clothing line and promotional appearances.
No custody arrangements for their eight-month-old daughter, North, are included in the prenuptial document.
The insider added: "The couple are focused on the wedding and looking forward to spending the rest of their lives together. Kim is head over heels in love with Kanye, and knows this is forever.
Despite having been married twice before, Kim is treating this wedding as her one and only."
Kim and Kanye are said to be marrying in Paris, France on May 24.
