It's no secret that Lisa Rinna and Kim Richards aren't the best of friends, and during the reunion, it looks like Richards is spilling a few secrets about Rinna's husband.

This is the same drama that escalsted during the ladies' trip to Amsterdam. During their dinner, Richards said that she would reveal a massive secret about Rinna's husband if she continued to question her sobriety.

Rinna clearly wasn't too happy that her co-star continued to make her husband a topic of discussion, and then Rinna tried to attack Richards and then threw a wine glass across the table.

Clearly the drama between the two ladies is far from over and things are bound to get nasty when part two of the season 5 reunion airs.

While the drama has gotten pretty intense, Rinna has managed to poke fun at herself and despite rumors of infidelity, she recently took to Twitter to joke that if her husband did cheat on her, it was with one of her other personalities.

Part 2 of the Real Housewives of Beverly Hills season 5 finale will airs on Tuesday, April 7 at 8 p.m. on Bravo.
