Cynthia Nixon strolls through NYC's NoHo district with wife Christine Marinoni... before she begins role as Nancy Reagan

Cynthia Nixon and her wife Christine Marinoni took a casual, make-up free stroll through Manhattan's NoHo district on Thursday.

The downtown power couple - who are parents of five-year-old son Max - will celebrate their fourth wedding anniversary on May 27.

And while the 50-year-old actress rocked a black T-shirt and flared dark rinse jeans, the 49-year-old education adviser for Mayor Bill de Blasio opted for a mini-skirt with her lavender top.
