Actor and screenwriter Tyler Perry has paid tribute to Whitney Houston's late daughter Bobbi Kristina Brown in a touching video, shared more than a month after her death. In addition to a personal quote from the 22-year-old, the footage features never-seen-before photos taken throughout her short life.

Alongside the video, which he posted on Facebook, Perry, 45, explains that he had been asked by The Houston Estate to share the clip which was shown at Brown's private funeral in August 2015. He added: "On behalf of the Brown and Houston families, we would all like to thank you for your prayers and support. God bless."

Hinting at the sorrow Brown experienced following the death of her mother Houston in February 2012, the three-minute video begins with a quote from Brown, which says: "I hope you feel my love, pain, beauty, agony at times, blessings all the time. No one understands me. And I don't expect them to, but I will try to spread my love and my story through words and this blessing of a powerful voice mum has given me."

The video then descends into a montage of photos starting from Brown's childhood, to happy times with her famous mother and father Bobby Brown including a family snap at Disneyland, as well as a sweet image with her grandmother Cissy Houston. The clip ends with a picture of Brown blowing a kiss with the caption: "Goodbye for now."

After spending six months in a medically-induced coma, Brown died on 26 July at the Peachtree Christian Hospice in Atlanta. The aspiring actress was found unresponsive in a bathtub at the Roswell, Georgia townhouse she shared with her boyfriend Nick Gordon. A cause of death is yet to be revealed due to a medical examiner failing to find any significant injuries in the initial post-mortem examination.

The examiner's office said in a statement released to People magazine in the days after Brown's death: "The death of Bobbi Kristina Brown has been reported to the Fulton County Medical Examiner's Office in accordance with state death investigation laws requiring investigation of known or suspected non-natural deaths.

"Because the events at her home leading to her death occurred in Fulton County (Roswell), her death has been reported to the Fulton County Medical Examiner for determination of the cause, manner, and circumstances of death. Despite the long interval between her being found unresponsive and her death, an autopsy will still be necessary to further evaluate possible causes of death or contributing factors."

Since Brown's death, reports have claimed that police are planning to launch a murder investigation with Gordon, 25, allegedly a suspect.

The Houston estate asked if I would share this tribute that I put together for Bobbi Kristina's private funeral. On behalf of the Brown and Houston families, we would all like to thank you for your prayers and support. God bless,
