Bobbi Kristina, Whitney Houston's daughter, is engaged to a guy named Nick Gordon. Whitney basically took Nick in and raised him from a young age, but never officially adopted him. Whitney used to refer to him as her "son."

Bobbi Kristina wrote on Facebook recently:

"People need to seriously stop judging my relationship. Pretty sure it's my own decision who I want to be with. Yes, my relationship may not be perfect. We will have rough patches, just like every other relationship. And we have had our rough patches. You may or may not agree with my relationship. You may or may not respect it. Judge me, go ahead. Your opinions are yours and mine are mine. It is my life and not yours. The decisions I make have nothing to do with you. Goodnight."
