Be of Good Cheer

Friend of the evening: Shay

You'll see Shay and Amy hard at work in the kitchen.
The very fact that Amy is posting this picture of herself shows that she has no pride.
Question: Who do you think Amy is talking to on the phone?
(Hint: the person has a last name that is also a geographical formation, she has a first name that is the same as a close relative of Amy's, she has a middle name that is often included in country western songs and musicals...)
