Bobby Brown opens up about the death of daughter Bobbi Kristina Brown (Video)

Less than a year after the death of his daughter, Bobby Brown is opening up in a new interview about the heartache of losing Bobbi Kristina Brown.

The singer spoke with ABC’s Robin Roberts on 20/20 about the eerie similarities between the deaths of Bobbi Kristina and the death of his ex-wife, her mother Whitney Houston, three years prior.

“The same thing that happened to my daughter, it happened to Whitney,” Brown said in the emotional interview. “My baby’s gone. The hardest thing I had to do in my life was tell my daughter to let go.”

Bobbi Kristina was found unconscious in a bathtub on Jan. 31, 2015. She was placed in a medically induced coma and died on July 26, 2015. Houston was found unresponsive in a bathtub on Feb. 11, 2012 and was pronounced dead at the scene.

Brown’s full interview will air on Tuesday at 10 p.m.
