Whitney's daughter finds love with her 'adopted' brother

TRAGIC Whitney Houston's teenage daughter has reportedly found love with her "adopted" brother amid claims that they are engaged.

Bobbi Kristina (18) was seen yesterday sporting what looked like a huge engagement ring when she and Nick Gordon (22) went out to get pizza.

Onlookers were amazed to see the pair share a romantic kiss. It's just weeks after the funeral of superstar Whitney who was found dead in a hotel bath. The singer raised Nick as her own from the age of ten after his real mother could not cope. Although he was never officially adopted, he has always been referred to by Bobbi, the star's only child, as her "big brudder" while he called her "little sis".

Their relationship is said to have now developed into a full blown romance as they comforted each other in grief at their mum's suspected overdose of prescription drugs.

Bobbi's grandmother Cissy (70) is said to be furious.

A bystander who saw the couple in Atlanta, Georgia where they share Whitney's old house said: "Bobbi was gazing up at him adoringly."

She pulled Nick in for a kiss as they entered the restaurant and he opened the door. One source said: "Nick is the only person she trusts after the tragedy." Nick pointed out on Twitter that they are not blood relatives. He said: "Yeah, we got a little closer and what!!! All the haters that don't know us or the real story."

Houston, whose cause of death has not yet been officially determined, was found unresponsive in water in a bathtub in her suite at the Beverly Hilton Hotel on February 11 and later pronounced dead.

Bobbi Kristina, Houston's child with her ex-husband Bobby Brown, told in recent days how she is comforted by the spirit of her mother.
