"It is too early to say if Whitney is going to perform, but I would hope she would be in the running," Davis added. "She looks radiant and is clearly together."

"She is talking enthusiastically and is articulate. We are going to make a great album. In my opinion, the best singers in the world are Aretha [Franklin] and Whitney. That's not to knock Mariah [Carey]. Mariah is a friend of mine, but I think Mariah would even say those two are the best."

Davis refused to comment on her Whitney Houston with Bobby Brown, but admitted friends and family were relieved to see Houston in such fine form at the Society of Singers tribute to Johnny Mathis last month.
