The aspiring actress was found unconscious in a bathtub two years ago and Nick has marked the occasion by reiterating his love for Bobbi Kristina, who died in July 2015, aged 22, after spending months in a medically induced coma.

He wrote alongside a picture of him kissing his ex-girlfriend: "You're the first thing I think about when I wake up and the last thing I think about before I go to sleep. I love&missyou RIH my angel. (sic)"

In November, Nick was ordered to pay Bobbi Kristina's family $36 million after he was found to be legally responsible for her death.

Nick was not in court throughout the case, and Fulton County Superior Court Judge T. Jackson Bedford said because he had failed to appear twice, anything alleged by the plaintiff was admitted through omission.

As a result, he agreed to award damages to Bobbi Kristina's estate, who had initially been seeking $40 million.

The judge heard testimony from Bobbi's father, Bobby Brown, as he assessed the losses and attempted to place a value on the deceased's life.

He said: "To determine the value of a life is pretty difficult. So the court has been back there primarily struggling with that particular issue."

The damages awarded in the civil case - which alleged Bobbi Kristina died due to a violent altercation with Nick, "after which he placed her in a bathtub, unconscious, after he injected her with a toxic mixture" - included $15 million for present value of life, $13.8 million for pain and suffering as a result of assault, $250,000 in punitive damages, $1.37 million for assault and battery and $1.575 million for money taken from an account.
