Cuomo spokesman Josh Vlasto said Lee, Cuomo's girlfriend of five years, will not be referred to as the first lady and she will not have any official duties or staff, the New York Daily News reported Friday.
"Sandra would never expect any taxpayer dollar to support the contributions she makes nor would she want to burden the state in any way," Vlasto said.
Etiquette experts agreed with the decision not to call Lee the first lady.
"I'm all for modern takes on partnerships, but in this case, unless you are married, I'd refrain from using the title first lady," said Anna Post of the Emily Post Institute.
