All of you who have not married a sibling, step forward. Not so fast, Bobbi Kristina Brown and Nick Gordon... Okay, to be fair, these two are not blood relatives. Gordon was a sort-of adopted member of the Brown family, where as Bobbi Kristina Brown is the daughter of Whitney Houston and Bobby Brown. Because Gordon was never officially adopted, it took a bit of the weirdness out of it - but just a bit, since they had been raised together by Houston. The two announced their involvement in 2012, though Gordon stated shortly after that they had reverted back to just being friends. However Brown would later announce their engagement, and they were married apparently in secret at the start of 2014. Getting a quick start on married life in the tabloids, Gordon was arrested just weeks ago for driving under the influence of alcohol and other charges after flipping his SUV. Luckily no one was hurt.
