The reality star joins the list of people grieving Monday's tragedy.
Like everyone else, Kim Kardashian West is struggling to cope with the bombing at Ariana Grande's concert in Manchester, U.K., on Monday night.

"I'm praying for everyone in Manchester," the 36-year-old mother of two added. "This is truly so senseless & heart breaking."
Kardashian West, who is a big fan of Grande's, brought her 3-year-old daughter, North, to the Los Angeles stop on the singer's Dangerous Woman tour at the end of March, where the three palled around backstage.
Grande, meanwhile, is heartbroken after the explosion, which left 22 dead and over 50 injured. CBS News reported more details from the horrifying incident.
“She’s an absolute wreck,” a source close to the star told ET. “She cares more about her fans than anything.”
