After being engaged for over a year, 20 year old Bobbi Kristina, the only child of late singer Whitney Houston, has married her adoptive brother and longtime friend, Nick Gordon. She  took to twitter yesterday to announce their marriage and show off their wedding bands.
Her relationship with nick generated so much controversy among relatives and friends asking if her mother would have approved because Whitney cared and took Nick in as a child. they both  lived like 'brother and sister' for years before Whitney's passing. Congrats to them
