LOS ANGELES, Feb 20: Reality TV star Kim Kardashian, 40, has filed for divorce from rapper Kanye West, 43, who has been battling mental issues for a long time. It will not be an acrimonious settlement for the celebs, but a smooth affair going by the prenup, according to gossip sources. It has been a long time coming. Kim will have the joint custody of the four kids and there is no dispute, they say.

Last year suddenly he had joined the presidential race and subsequently his depression went out of control, on stage weeping, sobbing, sniffing and dabbing at his eyes, shouting out incoherent episodes from his subconscious. Some said it was bipolar. He was reportedly locked up at home by Kim. His problem continued. They have been living separately for some time.

Married in 2014, they have four kids - North, Chicago, Psalm and Saint. Earlier Kim was married to music producer Damon Thomas and they divorced in 2004. Later she married Kris Humphries in 2011. This is her third divorce.

Kardashian had come into fame with the reality TV series, 'Keeping Up with the Kardashians' while Kanye was a Chicago-raised rapper and record producer. He has won 21 Grammys.

What may be a hitch is the distribution of the vast real estate lying across the country, from Los Angeles to New York, Miami to Wyoming.

In Hidden Hills, on Los Angeles outskirts, lies the all-white $60 million mansion, an empire in itself with all surrounding plots of neighbours bought up to ensure foolproof privacy. That is the couple's huge residential complex. She wants it because the kids are growing up there.

Over a dozen pricey properties mostly located around Los Angesles and some farther in New York city like his bachelor pad, vast tracts in Wyoming and a condo in the east on a Miami beach, strewn all across the US. One of the richest couples in entertainment. People who are in the know of things say the separation is amicable. Overdue for over a year. However, the plea has only just been filed.
