Whitney Houston's Aunt -- The Woman Who Tried to Save Her

Whitney Houston's aunt Mary Jones -- the woman who discovered the singer's body in the hotel bathtub, pulled her out and tried reviving her -- arrived at LAX yesterday to fly back east for the singer's funeral.

TMZ broke the story ... Whitney's aunt, Mary Jones, was in Whitney's room, laid out her dress for the Clive Davis party and then left for 30 minutes. When she returned, she knocked at the bathroom door and entered to find Whitney submerged in the bathtub.
