Feeling sad for Bobbi Kristina Brown, family: Whitney Houston's mentor Clive Davis

Whitney Houston's mentor and close friend Clive Davis says it pains him to see singer's daughter Bobbi Kristina Brown battling for her life.

Davis fostered Whitney as she was a teenager, when she joined the music world. She died three years back in her hotel room at the age of 48. Her 21-year-old daughter is on life support since last week, after being found unconscious in a bathtub at her home in Georgia. A cousin of Bobby tweeted that chances of her survival seemed less.

"It's very painful and heartbreaking to see the family go through such pain again," Davis said, comparing Whitney and her only child's state. The record producer said he misses Whitney. "I miss her personally, and I miss her as staggering performer," he said.
