Many people cry when they meet celebrities, especially the ones who have a crush on that particular individual. The degree of devotion to celebrities can range from a simple crush to a delusion that they have an intimate relationship with the star which does not exist. In some cases, this can lead to stalking behavior. This can easily switch to hatred of the previously loved celebrity, and result in attempts at violent attacks, one notable incident being the death of Rebecca Schaeffer by a stalking fan in 1989.
