She is on their payroll. Did an ad campaign for them. I think Bill Maher got one too...also on their payroll.
I dont know who is the bigger ass. I am leaning towads gnat, but after Bill dressed up as the crocodile hunter, with a sting ray in his chest and blood all over him for Halloween, id say he is giving gnat a run for her money. Peas in a Pod. Neither one of them have very many friends that are not related or not employees.
Bill Maher is probably making an animal rights statement out of the costume whereas Natalie Maines is just trying to please whatever crowd she happens to be around.
