Following months of speculations, reality TV star Kim Kardashian on Saturday filed for divorce from her husband, rapper Kanye West, after seven years of marriage. While the divorce is amicable, Kim has asked for the joint legal and physical custody of their four children, reported US media. Since the couple had signed a prenuptial agreement,the splitting up of their $2.1 billion combined assets will be easier, reported Forbes. With both Kim and West owning and operating their individual businessKKW Beauty and Yeezy respectively, they are expected to retain the ownership and income from the ventures. However, things will become complicated once their shared assets come into play such as their Calabasas mansion that has an estimated $30,000 bathroom sink, although, items like these contribute under 5% of their shared assets. Among the pair, West is worth more, most of which is from his shoe brand Yeezy that is known for its high end sneakers costing a minimum $200 a pair. Adidasmanufactures, markets and distributes the shoes while West receives 11% of the annual revenue. According to a Forbes estimate, Yeezy wasworth $1.26 billion in April 2020. Unlike West, Kim's asset is said to be more liquid. She has a 72% stake in her cosmetics company KKW Beauty that amounts to $500 million. Shesold 20% of KKW Beauty to cosmetics giant Coty and got $200 million in return. The couple co-owns several homes as well as mortgages such asa Calabasas mansion in Los Angeles County, Miami condo and two ranches in Wyoming. They also own art, cars and jewelry worth millions.
