The pair constantly clashed on 'The Real Housewives of Beverly Hills' and the 56-year-old star has admitted relations between them haven't improved since Brandi quit the show.
During an appearance on 'Watch What Happens Live', Lisa was asked whether she still talks to the 43-year-old star and confirmed their relationship is non-existent, adding: ''[I] got to know the block button.''
While Lisa has also been known to clash with Yolanda Hadid - the mother of Gigi and Bella - in the past, she admitted relations between them are ''better'' than they were.
Speaking about the 52-year-old TV personality, who is suffering with Lyme disease, Lisa said: ''[She] seemed to be doing much better.''
Lisa also hinted she clashed with Lisa Rinna - who also didn't get along with Brandi on the show - on the new series of 'The Real Housewives of Beverly Hills', but insisted fans will have to watch the series to find out exactly what happens.
However, she did say: ''It was hard to go back because I felt like I took a beating.''
Lisa signed up for the latest 'RHOBH' season despite speculation she had quit the Bravo show because she was unhappy with the ''negative vibes'' in the last series.
Yolanda quit the programme after producers reportedly told her she would be demoted to a friend of the show rather than a main star in the upcoming season, but it was stressed there was no ill feeling between the star and the production team.
Announcing her exit on Instagram, she wrote: ''I would have loved a more graceful exit then ''Season 6'' but sometimes we don't get to control the ending of the chapters in our life.............. I am leaving what's over without denying its past importance in my life. I believe that every exit is an new entry and with that in mind I say goodbye to my @Bravotv Family as I continue to focus on a my recovery, my children and bring back the privacy within our Home (sic)''
