Whitney Houston’s daughter, Bobbi Kristina and her adopted brother, Nick Gordon are officially married! But reports say her grandmother; Cissy Houston is not okay with the wedding. The new couple earlier told reporters that Cissy gave them her blessing but now, it’s allegedly a ‘big lie’.

According to TMZ, "Bobbi Kristina and Nick Gordon are now married. They also claimed they attended a Sweet 16 soiree, and that's where Cissy (grandmother) gave her thumbs up. But our Houston family sources say they were at the party and neither Bobbi nor Nick ever asked Cissy for her approval."

Following recent reports, Granny Houston was PISSED when she found out the two tied the knot last week ... but realized there's nothing she could do it about it.If you were the Grandma, what would you do to Bobbi?
