Bobbi Kristina, Nick Gordon Relationship Kept Cissy Houston From Whitney Houston Tribute?

Cissy Houston, the mother of late singer Whitney Houston who died last February, was reportedly missing in action from the Grammy tribute to the late singer earlier this month because of some strains with the deceased entertainer's daughter Bobbi Kristina Brown.

Houston, 79, is reportedly upset with her granddaughter Bobbi Kristina, 19, who is dating her adopted brother Nick Gordon, 22. However, some rumors have surfaced about the pair being engaged after a preview of their upcoming reality television show "The Houstons: On Our Own" featured Bobbi Kristina telling her family "we're engaged."

The news of this engagement reportedly upset Bobbi Kristina's grandmother so much that she declined to appear at the tribute show for her late daughter called "We Will Always Love You: A Grammy Salute to Whitney Houston." The elder Houston reportedly refused to attend the show scheduled to air on CBS on Nov. 13 because Bobbi Kristina and her boyfriend would be in attendance, according to Radar Online reports.

"Cissy really wanted to be there for Whitney," a source close to the family reportedly revealed to Radar Online. "But she's just too angry with Bobbi Kristina right now. Cissy and her oldest son Gary couldn't stomach sitting next to Bobbi Kristina and Nick."

While a Houston representative denied that Bobbi Kristina and Gordon were engaged in a Radar Online report saying "you have to watch the show," several members of the family have spoken out against the young couple's union.

In a promotional clip for their upcoming reality television show, Cissy Houston's son Gary Houston tells his niece's boyfriend about the concern the family has about his relationship with Bobbi Kristina.

"No one knew that from a godson you would turn into a boyfriend," Gary tells Gordon in the preview. "No one knew that."

Pat Houston, Gary's wife, also expresses her issues with the young couple after Bobbi Kristina announces a potential engagement in a preview of the reality television show.

"Engagement," she questions in a preview clip for the show. "This is not acceptable."

While neither Cissy nor Bobbi Kristina confirmed any immediate strife that led to the absence of her appearance at the late Houston's tribute show, the deceased singer's mother admitted that the family was enduring an emotional time much like other families.

"We laugh and we cry," Cissy said in a preview of the show scheduled to air Oct 24. "There's a lot of turmoil in everybody's family."
