An autograph is a celebrity signature and not a personalized message. Celebrities, at their discretion, may be able to write a few additional words in addition to their signature but it is not guaranteed.
Because of health and safety concerns, many celebrities do not want any physical contact with fans such as hand shaking. Kissing, hugging or other inappropriate touching is NOT allowed. Inappropriate images may not be signed by the guests and could also cause your removal from event.
