Whitney Houston's daughter celebrated her 17th birthday yesterday in Australia -- and her soul diva mother marked the occasion by singing to her in front of a stadium packed with 12,000 people.
According to People, halfway through Whitney's show last night in Adelaide, a cake was rolled out and she sang "Happy Birthday" to daughter Bobbi Kristina Houston Brown, who joined her on stage.
This time, Bobbi was the queen of the night.
