The syndicated show's producers said Winfrey gave the designer and TV personality an intimate tour of the tea house, lavender field and rose garden at her Montecito, Calif. home. She also sat for an interview with Berkus to air Tuesday.
"Well this is a new day, you interviewing me … . How weird is this?" Winfrey said during their sit-down chat.
Berkus was a frequent guest on "The Oprah Winfrey Show" before he started up his own series, which is co-produced by Winfrey's Harpo Productions and Sony Pictures Television, last year.
Winfrey's show is winding up its 25th and final season.
