Since radar posted the uncle’s full name and more quotes i am guessing he is real. He says he knew DD before she did and that they all hang out together. What kind of family member talks to tabloids about you? She had to have known.

They have a legit uncle who is speaking too much but still telling them David isn’t dating his niece and a tumblr stalker who saw them walk in the streets of Vancouver. That’s all it is. It’s a mess, and I’m sure the uncle is proud of himself and got a nice amount of money.
All in all, I hope David will distance himself from that girl and her chatty family now. That’s something he really didn’t need at this point of his life.
