See Inside Luann de Lesseps' Glamorous Sag Harbor Bathroom

Though she's currently a reigning queen of cabaret, Luann de Lesseps has a background as a nurse. (Here's proof.) So at a time when a thorough hand-washing could save lives, The Real Housewives of New York City cast member is making sure everyone knows how to scrub up good. 

In a March 17 Instagram Story filmed in the bathroom at her Sag Harbor home, Luann led a very timely tutorial. "I figured I would do a proper hand-washing for you guys, as I'm a nurse," she said. First, she leaned over her white marble countertop to turn on the faucet. 

Standing in front of an ornate, silvery mirror hung on a wall of white tiles, Luann shared, "First of all, we want to get really hot water, get some good soap, and you want to wash the front and back of your hands vigorously, for a good 20 seconds... This will keep down your chances of getting the coronavirus, so we can get out of our houses." 

And while some people are singing the standard birthday song to help pass those 20 seconds, Lu had another song pick. "Chic, c'est la vie, c'est bon, c'est bon," she chanted as she scrubbed.
