Whitney Houston's daughter, Bobbi Kristina marries adopted 'brother'

After being engaged for over a year, 20 year old Bobbi Kristina, the only child of late singer Whitney Houston, has married her adoptede brother and longtime friend, Nick Gordon. Bobbi took to twitter yesterday to announce their marriage and show off their wedding bands.

Her affair with Nick, 24, has overtime generated a lot of controversy with relatives and friends asking if her mother would have approved because Whitney cared and took Nick in as a child. So Bobbi and Nick lived like 'brother and sister' for years before Whitney's passing. Big congrats to them!
