A source close to the family shot down rumors that the Houston and Brown clans had gathered at the 21-year-old's bedside to say goodbye, and denied reports in the Daily Mail that life support measures had been ended.

The family has also denied rumors of any in-fighting, and have reportedly agreed that father Bobby Brown -- who turned 46 on Thursday -- will be the one to make any decision regarding his daughter.

Bobbi Kristina was discovered face down in a bathtub of water on Jan. 31, just days shy of the third anniversary of the death of her mother, Whitney Houston.

At a tribute concert held in Hollywood on Wednesday night, Bobbi Kristina was on the minds of some of her mother's dearest friends.

"I think the biggest part of it is that this baby didn't have the opportunity to mourn her mother," Kelly Price told ET.

Price, who co-hosted the "For the Love of R&B: A Tribute to Whitney Houston" pre-GRAMMY party along with Faith Evans, was a part of Whitney's last known performance. The two sang an impromptu duet at a private party two nights before Whitney's death.

"When [Whitney] walked off the stage, she looked at me, she blew me a kiss and she said, 'Goodbye.'" Price remembered. "I didn't know it was goodbye."
