Here’s the Real Reason Kim Kardashian Finally Filed for Divorce From Kanye West.

Kimye is really, truly over.

Kim Kardashian filed to divorce Kanye West on Friday, Feb. 19, after six years of marriage, E! News confirmed.

The spouses have agreed on joint custody for their four kids, North, Saint, Chicago and Psalm, and neither Kim nor Kanye are contesting their prenup, according to a source close to Kim.

The source exclusively tells E! News that the split is “very amicable” and gave insight into how the Keeping Up With the Kardashians star is coping. “Kim is doing OK,” the source says. “She’s mostly worried about her privacy and kids. She’s a mama bear and protective of her kids.”

Kim’s attorney Laura Wasser, who is representing her amid the divorce, could not be reached for comment.

E! News reported last month that while the 40 year old was considering divorce, the couple had been in marriage counseling. So what finally changed and made her pull the plug?

The insider explains, “Kim was just tired of waiting. She tried to give it a chance. She wanted to do this last year. She gave it plenty of time but it’s just time to move on.” And before you start thinking of thoseJeffree Star rumors, think again. Adds the insider, “There were no affairs. No one did anything bad. They grew apart.”

Kim and Ye are committed to co-parenting, although the “Famous” rapper “hasn’t been around much,” the source says. Their four kids have mostly been with Kim at her home in Calabasas, Calif., in recent weeks.

“North has some understanding of what’s going on,” the source adds. “But mostly the kids have always seen them apart so it isn’t super surprising.”
