First, I will let you all come to terms with the fact that Kardashian and West have already been married for three years. For those fans that don't have her app or access to her official site, Kardashian took to her Instagram and Twitter to share another sweet photo of herself and West with a simple message, "3 down, a lifetime to go". She also expressed deep sorrow at the attacks in two other posts, writing, "I'm praying for everyone in Manchester". She told her 52.5m followers: "I can't imagine the fear and agony these parents must be going through searching for their kids".
"This is truly so senseless & heart breaking". Kim deleted the post after an hour, but the screenshots live on.
