Whitney Houston’s daughter Bobbi Kristina is seen in public for the first time with new love Nicholas Gordon – her ‘adopted’ brother. The pair went public with their relationship, kissing and holding hands, as they collected a take-out pizza dinner near their home in Atlanta, Georgia.

The relationship is controversial because Whitney raised Nicholas as her own son since he was 12-years-old and Bobbi is said to have always looked up to him as her ‘big brother,’ although Whitney never formally adopted him. Bobbi is Whitney’s only child and soul heir – the result of the singer’s troubled 14-year marriage to singer Bobby Brown.

Whitney, 48, was found in a Beverly Hills hotel room bathtub on the eve of the Grammy Awards. Investigators found several bottles of prescription medication in the room, and tests were being conducted to determine the cause of her Feb. 11 death.
