Kim Kardashian Has Known About Kanye West's Relationship with Irina Shayk for 'Weeks,' Source Says

Kim Kardashian is only thinking about her children on the heels of the news that ex Kanye West is seeing model Irina Shayk.

The Keeping Up with the Kardashians star, 40, filed for divorce from the rapper, 43, in February, following a tumultuous year. The former couple, who wed in May of 2014, share daughters North, 7½, and Chicago, 3, and sons Saint, 5, Psalm, 2.

After West and Shayk, 35, were spotted together in France earlier this week, a source says that Kardashian has known about their budding romance "for weeks."

"It doesn't bother Kim that Kanye is dating," the insider says. "Her only concern is their kids. She wants Kanye to be present and spend as much time with them as possible. The kids love when Kanye is around."

The source adds, "Kim doesn't want a new girlfriend to distract Kanye from spending time with the kids."

A second insider said that the new couple met "a while back" when they crossed paths in the fashion industry.

Shayk previously modeled for Yeezy and appeared in his music video for "Power." West also name-dropped her in "Christian Dior Flow" with the lyric "I wanna see Irina Shayk next to Doutzen" back in 2010.

"Irina isn't friends with Kim at all, so there's no weirdness there," added the second insider.
