Past declarations of lesbianism. That honeymoon in Cuba. The shunning of a high-society balls.

With tongue in cheek and a roll of the eyes, Mayor Bill de Blasio's wife, Chirlane McCray, touched on such topics in a video released by the mayor's office Thursday to promote a live Facebook question-and-answer session that she is hosting Tuesday at 11 a.m. to promote mental health.

A sampler:

* "Why didn't you attend this year's Met Ball?"

Answer: Sigh. "It's a long story. But bottom line: Rihanna stole my dress!"

The first couple have largely been no-shows at high-society events like the Met Ball, a gala that raises money for the Metropolitan Museum of Art's Costume Institute.

* Does de Blasio, a Democrat, call her "first lady" at home?

Answer: They call each other "comrade."

* "Are you still a lesbian?"

No answer; just an eyeroll.

McCray penned an article for Essence in 1979 titled "I Am a Lesbian." A dozen years later, she met and fell in love with de Blasio.

Tuesday's Facebook session with the online publication Mic will address an issue the mayor's wife had made a cornerstone of her public life. The first couple's daughter, Chiara de Blasio, has gone public with her own struggles with anxiety, depression and drug use to raise awareness.
