Bobbi Kristina Brown is not engaged to Nick Gordon and she is simply wearing her mother’s ring, says her rep

Bobbi Kristina Brown, Whitney Houston’s daughter, sparked controversy as she and “her adoptive brother” Nick Gordon are set to wed after stepping out with a diamond ring on her wedding finger.

However, a spokesperson for Bobbi Kristina Brown said yesterday that Whitney Houston’s only daughter is not engaged and the ring is actually her late mother’s.

Bobbi Kristina’s rep said: “Bobbi Kristina is not engaged. She is simply wearing her mother’s ring.”

The denial comes four days after reports surfaced that Bobbi Kristina Brown and Nick Gordon were planning on getting married.

Over the weekend the pair was spotted stepping out together hand-in-hand in Atlanta and last Thursday Bobbi Kristina was seen first sporting the ring as she kissed Nick Gordon on a date at a pizza parlour.

As part of Whitney Houston’s will Bobbi Kristina inherited all of her jewellery collection.

The denial from Bobbi Kristina’s reps come after reports that her grandmother Cissy Houston has slammed the pair’s relationship branding it “incestuous” emerged.

On Friday Bobbi Kristina, who is mourning the death of her mother, was spotted leaving an AT&T store with Nick Gordon, who Houston raised as her own for 10 years.

Bobbi Kristina and Nick Gordon looked happily in love and held hands as they entered and left the store, in their hometown.
