Luann de Lesseps of Bravo’s “The Real Housewives of New York” is meeting “Watch What Happens Live” host Andy Cohen at her home in Sag Harbor for her first formal interview since she and her husband announced their impending divorce.

The cable network Bravo announced Monday that the interview would air as the special “Watch What Happens Live One-on-One with Luann de Lesseps” on Sept. 6 at 11 p.m. De Lesseps formerly had a home on Highland Terrace in Bridgehampton, but last year purchased an 1835 Greek Revival on the water in Sag Harbor.

De Lesseps was previously married to Count Alexandre de Lesseps, with whom she had son Noel and daughter Victoria.
