Whitney Houston's mom, Cissy Houston ticked off about Bobbi Kristina's marriage

MStars recently reported that the daughter of the late Whitney Houston, Bobbi Kristina revealed that she tied the knot, with her "brother," Nick Gordon via Twitter.

Well now, the claws are coming out from Whitney's mother, Bobbi Kristina's grandmother, Cissy Houston. TMZ reports that Houston gave them her blessing to tie the knot, but apparently that is not true. 

Legendary R&B singer Bobby Brown's daughter is in fact now married to her adopted brother, claiming that they attended a Sweet 16 party and that's where Houston gave her approval. 

But Houston family sources are revealing that they were indeed at the party, but Bobbi Kristina nor Nick ever asked for permission from her grandmother to go get married. 

Instead Houston is ticked off that the couple are married, but she realizes there is nothing that she can do about it. After all Bobbi Kristina is an adult, she is not the little girl we heard singing along to her mothers' hit songs, like "My love is your love."
