Bobby and Tina Brown are absolutely wrong ... Bobbi Kristina is not off life support and remains unresponsive ... this according to the Houston family. Sources connected with the Houstons tell TMZ, they have no idea where Bobby Brown is getting his information that Bobbi Kristina was awake, nor do they know why Tina said she's awake and no longer on life support. Gossip Cop first reported the conflicting positions between the Browns and the Houstons. We're told the Houstons are clear ... "She's in the exact same condition she was in when she went into the facility." They say there is "minimal" reaction ... an occasional eye blink, but that's it. The Houstons say Bobbi Kristina is still on a ventilator.
