Tonight’s Billboard Awards will feature tributes to Donna Summer, Adam Yauch and Whitney Houston. It seems that only one of those tributes will be marred by fighting family members. It seems that Pat Houston wanted to edge out Bobbi Kristina from accepting the Millennium Award on behalf of her mother. According to TMZ , the producers of the show asked Bobbi Kristina to make the acceptance speech and Pat Houston is not having it. Other sources say both women were asked to accept the award together. TMZ’s source is saying this is Pat trying to get publicity for her reality show. Just when you think people can’t get any lower, they always manage to surprise you.
