Whitney Houston left her entire estate to her 19-year-old daughter. An undisclosed amount of money will be placed in trust until Bobbi Kristina Brown turns 21. She'll receive a portion of the inheritance then, more at the age of 25, and the rest at 30. The trust administrator—the singer's sister-in-law and manager Patricia Houston—can release money earlier for tuition and the purchase of a house, reports AP. Houston's will, revealed in an Atlanta court, was written while she was married to Bobby Brown about a month before the birth of the couple's only child. Houston died in a bathtub in a Beverly Hills hotel last month. Her daughter is grappling with some of the same substance abuse demons that haunted her mom, say friends. (More Whitney Houston stories.)
