Why is Gia Khay so angry?
First, it is not clear that Gia is really an angry person; she may just be a spoiled person who is accustomed to getting her own way and sulks or lashes out when things don't go according to her plans; or all of this may be part of her "act," since she certainly seems like someone who knows how to get publicity for herself. The TV audience was first introduced to Gia when she was part of a VH1 reality show called "You're Cut Off," which debuted on June 9, 2010.

The plot was that nine self-centered young women had been unexpectedly cut off by their families, who were tired of how spoiled and entitled these young ladies had been acting, and wanted them to be taught a good lesson about living more independently and treating other people better. During an eight-week "rehabilitation" process, they were expected to perform a number of tasks (like shopping on a very restricted budget, cleaning the house, helping the homeless, etc), which were intended to teach them how to act in a more appropriate and compassionate manner. We have no way of knowing whether the lessons of the show really did have a lasting impact on the nine participants.
