Aiming at the bull's-eye? Kim Richards and Lisa Rinna get into a heated conversation about the former child star's sobriety in the Real Housewives of Beverly Hills' season 6 finale on Tuesday, April 12, as seen in Us Weekly's exclusive sneak peek.

In the preview clip from the Bravo series' new episode, Richards (making her third return cameo of the season) admits to Rinna that the season 5 reunion "was not a very good time." The two had exchanged heated words at last season's reunion, with Richards quipping that there is "something f--king wrong" with the Melrose Place alum.

Richards, 51, confronts Rinna, 52, in the new footage over the fact that the soap star was "enraged" that Yolanda Foster had skipped a dinner party the same day she got lunch with Richards and Brandi Glanville. Rinna replies, "Kim, it's your choice to live your life the way you live your life ... I want you to get better."

The Escape From Witch Mountain actress — who has struggled with her sobriety throughout the course of the series — fires back, "I am better. I felt like that's a dart, like you just threw a dart at me, honestly."

Watch the heated conversation in the video above.

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