Whitney Houston's Mother Will Not Attend Clive Davis' Grammy Party: To Be Invited Was 'Obscene' (UPDATED)

Whitney Houston tragically passed away just hours before mentor Clive Davis’ annual Grammy party last year (where she was scheduled to appear), sending shockwaves through the music community.

Cissy Houston, the late superstar’s mother, will not be attending Clive’s Grammy party this year, and in a new interview with Access Hollywood, the still-grieving mom said she was disgusted by the invite.

“I got an invitation to the party — which is the most obscene thing,” Cissy told Access at the unveiling of four new wax statues of her legendary daughter at Madame Tussaud’s in New York City on Thursday. “I don’t know why they would want me to come to the party in which she died, you know? Unheard of.”

Adding, “I guess maybe he just sent me a copy for remembrance sake.”

In addition to skipping the party, Cissy will not be attending the Grammy ceremony itself, but said she will be tuning in to watch the awards on Sunday.

The Houston matriarch also opened up about the status of her relationship with granddaughter Bobbi Kristina, who recently Tweeted an angry reaction to the book Cissy recently penned about Whitney.

(“I find it 2b disrespect2mymother & me being her daughter won’t tolerate it,” Bobbi Kristina Tweeted last week.)

“She’s grieving. [She’s] really grieving,” Cissy said. “Bobbi Kris knows — she better know — that I love her. Anything I can do for her, I’ll be there. I wouldn’t say anything [bad] about my daughter. That’s MY daughter, whom I loved with all my heart.

“I love Krissy because she belongs to my daughter, all right?” she continued. “I think that she’s just grieving. That’s the only other thing I can say about it.”

UPDATE: On Thursday evening, a rep for Clive Davis contacted Access Hollywood and said Pat Houston and Whitney’s brother, Gary Houston, are expected to attend the Pre-Grammy Gala on Saturday night.
