Kim Kardashian and her rapper husband Kanye West were in Jerusalem's Old City Monday for the baptism of their daughter North West at the Armenian Cathedral.

"It's a baptism that will take place," Archbishop Aris Shirvanian told reporters gathered at the entrance to the church, according to i24 News.
