Bobbi Kristina Brown's former boyfriend, Nick Gordon, has died from a suspected drug overdose.
The 30-year-old's brother, Jack Walker, Jr., broke the news on social media on Wednesday.
"GOD WHY I DID I HAVE TO LOSE MY BROTHER ON NEW YEARS (sic)," he posted on Facebook, adding, "All I can do is cry."
He went on to pay tribute by sharing a series of photos of the siblings, and wrote, "I love you so much big brother I hope you heard me talking to you at your bedside you are with me and I can feel it I love you I love you I love you watch over me and your nieces (sic)."
Walker went on to reveal that Gordon had been hospitalised and he was by his brother's side when he passed away.
He has since confirmed his sibling's death in a statement issued to People.com.
"We are devastated by the loss of my beautiful brother," he said. "He leaves a void in the hearts of my family and his friends.
"Nick's battle in life was not an easy one. I will be forever grateful that my God afforded a small moment at the very end of Nick's life, and I was able to hold his hand as he journeyed on."
According to editors at The Daily Mail, Gordon suffered a series of heart attacks on Wednesday and was admitted to the intensive care unit at Altamonte Springs Hospital in Florida, where he was later pronounced dead.
Gordon was dating Whitney Houston and Bobby Brown's daughter, Bobbi Kristina, at the time of her drug overdose in January 2015, when she was found unresponsive in the bathtub of the home they shared in Alpharetta, Georgia.
She was placed in a medically-induced coma, but never woke up, and died in July 2015, aged 22.
Gordon was sued for wrongful death by Bobbi Kristina's father and her estate executor, who accused him of abusing the aspiring actress, and claimed he had given her a "toxic cocktail" of substances, which made her lose consciousness as she bathed.
He maintained his innocence, but in 2016, he was found civilly liable for Bobbi Kristina's death, and was ordered to hand over $36 million (£27 million) in damages.
