The aspiring singer and actress was found unconscious in a bathtub on 30 January, 2015.

Brown, the daughter of Bobby Brown and the late Whitney Houston, never regained consciousness and died later that year (Jul15).

Remembering his dead girlfriend on Twitter on Monday, Gordon wrote: "You're the first thing I think about when I wake up and the last thing I think about before I go to sleep."

He added a photograph of the couple kissing and added: "I love&missyou RIH my angel."

After Bobbi Kristina was hospitalised in January, 2015, Gordon was forbidden from visiting her by members of her family.

In September, Fulton County Superior Court Judge T. Jackson Bedford found Gordon "legally responsible" for her death after a wrongful death suit, supported by her father, was filed against him.

Gordon was ordered to pay $36 million (GBP28.8 million) in damages to her estate.
