Kim Kardashian West has filed for divorce, seeking to end her nearly seven-year marriage to Kanye West, a spokeswoman for Ms. Kardashian West said on Friday.
The spokeswoman, Christy Welder, would not elaborate on the filing, which would dissolve a celebrity union that came to be known as Kimye.
Ms. Kardashian West, 40, and Mr. West, 43, have four children: North, Saint, Chicago and Psalm.
Their marriage was an endless source of celebrity news, family turmoil and brand sponsorships, tracked incessantly by the media. Elements of their tumultuous relationship became fodder for occasional episodes of her long-running reality show, “Keeping Up With the Kardashians,” and was documented for millions on their Instagram and Twitter accounts.
Mr. West, the billionaire hip-hop artist and fashion mogul turned Christian revivalist, said last year that he was running for president, a move that perplexed and concerned some close to him. Mr. West had spoken in the past about his bipolar disorder.
Ms. Kardashian West had opened up about it for the first time days after Mr. West made a campaign appearance in South Carolina, during which he broke down crying. Writing on Instagram, she called him a “brilliant but complicated person” who has to deal with “pressure and isolation that is heightened by his bipolar disorder.”
Before their courtship became public in 2012, Ms. Kardashian West and Mr. West had known each other for roughly a decade. They were first introduced in about 2002 or 2003 by a mutual friend, the singer Brandy. The pair dated for two years before marrying in an opulent $2.8 million ceremony at Fort di Belvedere in Florence, Italy, on May 24, 2014.
