Reality TV star Kim Kardashian has filed for divorce from rapper Kanye West after almost seven years of marriage.

The 40-year-old TV star filed documents on Friday, according to TMZ, through her lawyer Laura Wasser but the date of separation was not mentioned.

She said the separation was “as amicable as a divorce can be.”

Kardashian is asking for joint legal and physical custody of their four young children: North, seven, Saint, five, Chicago, three, Psalm, 21 months.

Kim and Kanye started dating in 2012, became engaged in 2013 and wed in May 2014 in Italy after they had already welcomed their eldest daughter North.

This will be Kim’s third divorce as she was wed to Damon Thomas from 2000 until 2004 and she was married to Kris Humphries from 2011 until 2013.
