Whitney's mom Cissy Houston is not to happy about the party. She told Access Hollywood, "I got an invitation to the party, which is the most obscene thing. I don't know why they would want me to come to the party in which she died, you know? Unheard of. I guess maybe he just sent me a copy for remembrance sake."
