There was nothing politic about this Democratic fund-raiser.

Stars and drag queens took the stage at one of the most unbridled political events of the mayoral race — a Mother’s Day evening bash for Bill de Blasio.

“Amber,” who strutted onstage as Reba McEntire, joked that she and the candidate once tripped on acid while “riding horses naked through my pastures.”

Another performer gave de Blasio a pseudo lap dance at the venue, The Cutting Room in Midtown.

The LGBT fund-raiser was hosted by “Sex & the City” star Cynthia Nixon and actor Alan Cumming.

De Blasio’s staff estimated 300 supporters attended the event, at $25 each.
