Whitney Houston Tribute Takes More Somber Tone As Her Daughter Fights For Her Life

HOLLYWOOD (CBSLA.com) — Celebrities at a Wednesday night tribute to Whitney Houston expressed their concern for her daughter, Bobbi Kristina, who remains on life support in an Atlanta hospital.

It's been almost three years since Houston was found dead in a bathtub at the Beverly Hills Hotel.

But many celebrities at The Attic on Hollywood Boulevard Wednesday were also thinking about her daughter.

The 21-year-old was found unconscious in her bathtub several days ago.

Doctors say Brown has probably suffered serious brain damage.
