I am actually very annoyed with Gillian. Although Aaryn, Amanda, and GM all said very nasty things, I feel they are reality stars and everyone should be invited as long as they donate. I'm pretty sure Colton and Shannon Elkins have gone, and they have said nasty things in the past.
Just let them go. That was inside the house, and I am positive they have realized how bad what they said was. Plus, they have a lot of people who will donate for them.
