"Dance" Music (25 Questions) by BruceM

Question 23

"The [BLANK] is dancing with me, cheek to cheek
There's nobody here, it's just you and me
It's where I want to be
But I hardly know this beauty by my side
I'll never forget the way you look tonight."

What title heroine fills in the blank from that Chris De Burgh ballad?

Lady in Red
