Bobby Brown has spoken about losing his ex wife Whitney Houston and their daughter in the space of just three years.

Houston died in a hotel in 2012 after drowing in a bath following a cocaine overdose.

Their child Bobbi Kristina passed away in 2015 at the age of 22 after being found dead in her bathtub.

Speaking to US TV's 20/20, Bobby Brown - who split from Houston in 2007 - said the loss is "unimaginable".

He said: "I am completely numb at this time.

"Krissy was and is an angel. My family must find a way to live with her in spirit and honour her memory. Our loss is unimaginable."

The full interview with Brown is due to air on July 7.
