Remembering the pain. Lisa Vanderpump breaks down in tears while discussing her previous abusive relationship in part 2 of The Real Housewives of Beverly Hills' season 6 reunion on Tuesday, April 26, as seen in Us Weekly's exclusive sneak peek.

The Bravo series' preview clip shows Eileen Davidson telling the Sur boss, 55, that it was "incredibly offensive" for her to write in her blog in January that Davidson shouldn't have discussed on an episode that she was the victim of domestic violence. 

In the blog, Vanderpump, who is marred to Ken Todd, mentioned that she, too, had been in an abusive relationship.

When host Andy Cohen asks when the Vanderpump Rules star's abusive relationship took place, the restaurateur replies, "Oh, my god — I was 19, and I was threatened and physically hurt."

Cohen then asks how long the pair were together. "The relationship was quite a long time," replies Vanderpump, who proceeds to get very emotional in the clip.

Watch the heartbreaking scene unfold in the video above.

The Real Housewives of Beverly Hills airs on Bravo Tuesdays at 9 p.m. ET.
