Bobby Brown is angry at his sister's accusation that Pat Houston pushed daughter Bobbi Kristina's death, due to soaring medical expenses.
According to the sources, the 46-year-old singer claimed that Leolah Brown hadn't even been there to support his comatose girl, and was just making it all up, reported TMZ.com.
Brown thinks that Leolah has no clue about how Pat felt towards Bobbi Kristina's condition, and was only doing this for attention, added the sources.
