ET's Nischelle Turner spoke to Clive Davis after rehearsals for his legendary annual GRAMMYs party on Thursday, where he -- like everyone who was close to Whitney Houston -- had his mind on Bobbi Kristina Brown.

"I'm heartbroken that the Houston family is feeling such pain again," Davis told ET at the Beverly Hilton Hotel. "I've been in touch with [Whitney's sister-in-law] Pat and offering my support, solace and prayers. The family really requests privacy at this very trying time, and certainly I'm going to respect it and I'm sure everybody else will too."

Davis was Houston's mentor and it was hours before his GRAMMY party in 2012 that she passed away of an accidental drowning in a hotel bathtub at the Beverly Hilton, in which drugs and heart disease were also said to have played a part.

Bobbi Kristina was reportedly discovered face down in a bathtub of water on Jan. 31, just days before the three-year anniversary of her mother's death. She was found by Nick Gordon, her unofficially adopted brother, and friend Maxwell Lomas.

GRAMMY host LL Cool J also commented on the incident Thursday, telling ET, "The timing is unfortunate -- that it happened around this time of year. It does remind me [of Whitney's death] and brings back those feelings, but ultimately I just pray that [Bobbi Kristina] recovers, that she comes out of her coma and that her family rallies around her and gives her the support that she needs to get healthy again."

ET also learned that Cissy Houston, Bobbi Kristina's grandmother, was traveling to Atlanta to join family members at Emory University Hospital. Cissy, who is 81 years old, will be there through the weekend.
