All of the Real Housewives series feature relationship drama, but the scandals on RHOC have been especially intriguing.

1 /10: Slade Smiley & Jo De La Rosa

Original Housewife Jo De La Rosa was engaged to RHOC villain Slade Smiley long before he hit it off with Gretchen Rossi. De La Rosa has since admitted that she's annoyed with Rossi for breaking the girl code.

2 /10: Slade Smiley & Lauri Peterson

Smiley sure has a thing for Real Housewives babes! He had a fling with De La Rosa's co-star Lauri Peterson while he and his original RHOC fiancé were on a break.

If there's one RHOC couple that has attracted more criticism than Vicki Gunvalson and Brooks Ayers, it's Slade Smiley and Gretchen Rossi.

4 /10: Gretchen Rossi & Jeff Beitzel

Gretchen Rossi has been at the center of nearly as much relationship drama as Slade Smiley. Before she and Smiley joined forces, Rossi was engaged to Jeff Beitzel. A lot of people think that her relationship with Beitzel was more about money than romance.

5 /10: Vicki & Donn Gunvalson

Over the years, many of Vicki Gunvalson's critics have accused her of cheating on her ex-husband Donn with Brooks Ayers. These allegations were all but confirmed during a conversation between Ayers and Briana Culberson.

The big Gunvalson and Ayers scandal of Season 10 had less to do with their actual relationship and more to do with Ayers' cancer diagnosis, which most of the Housewives agreed was fake.

7 /10: Brooks Ayers & Briana Culberson

Ayers evidently had a thing for Gunvalson's daughter — he hit on her while she was pregnant!

8 /10: Tamra Judge & Simon Barney

8/10 :Tamra Judge & Simon Barney

Tamra Judge is currently very happy with her husband Eddie, but first, she had to exit her tumultuous relationship with ex-husband, Simon Barney. Many critics (including Slade Smiley) have accused Judge of cheating on her ex.

9 /10: Heather & Terry Dubrow

9/10 :Heather & Terry Dubrow

The Dubrows' marriage is far from perfect. Terry Dubrow once admitted to throwing out the 'D' word and threatening divorce.

10 /10: Shannon & David Beador

Shannon and David Beador's marriage was almost shattered by a cheating scandal. The two still have their issues, but they've worked hard to repair their relationship.
