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. The reality star tweeted out an old picture of herself, sister Kendall Jenner and Grande at a concert together, writing, "Concerts are supposed to be a place where u can let loose & have fun. So scary to not feel safe in this world. @arianagrande I love you." 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. "Broken," the 23-year-old singer tweeted on Monday. "From the bottom of my heart, I am so so sorry. I don't have words."
