Houston we have a problem!

The mother of the late Whitney Houston was so enraged with Bobbi Kristina Brown’s plans to wed “adopted brother" Nick Gordon she snubbed a star-studded tribute for the I Will Always Love You singer, the National Enquirer claims.

Cissy Houston, 79, refused to attend the Grammys’ Final salute for Whitney on October 11 at L.A.’s Nokia Theatre because Bobbi Kristina and Nick were scheduled to attend.

“Cissy really wanted to be there for Whitney,” revealed a source close to the family.

“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.”

The rumor mill has been in overdrive with reports claiming that Bobbi Kristina and Nick are engaged.

And in a promo clip from Lifetime’s new reality show The Houstons: On Our Own, Bobbi Kristina is seen announcing to family members: “We’re engaged!”

Despite that, her rep has denied the claims, adding: “You have to watch the show!”
