Does Kathie Lee Gifford have a drinking problem?

Or, perhaps if that isn’t common knowledge… is she rumored to have a drinking problem?
I watch very little television, and I never really have, so celebrity gossip isn’t a topic that I know much about. I just so happened to be watching the Today show, and she looks tanked.

I grew up with an alcoholic parent, so I can usually spot a functional alcoholic from a mile away. I know this is a silly question, but it made me curious to know if this is a common rumor or even a verified truth.
