“Be cool, don’t be all, like, uncool.”
Those words from Countess LuAnn de Lesseps will live in infamy -- and so will all the scandals surrounding her fellow Real Housewives this year!
ETonline is taking a look back at the seven scandals that totally rocked Bravo in 2015.
WATCH: All the Things That Allegedly 'Broke the Internet' in 2015
1. Teresa Giudice's Prison Sentence
The New Jersey star served nearly a year behind bars, but got out just in time for Christmas with her family -- and to write a tell-all book about her time in prison, set to be released in February.
2. Kristen Taekman's Husband Shows Up in the Ashley Madison Hack
Even Bravo-lebrities weren’t immune from the cheating site’s data breach. But, the RHONY stars stuck together through the scandal -- and their co-stars stood up for them.
“I don’t believe Josh has ever cheated on Kristen,” Ramona Singer told ET. “I see them as a really loving couple.”

3. Peter Thomas Seemingly Caught Kissing Another Woman
A short video clip of Atlanta star Cynthia Bailey’s husband seemingly kissing a woman in a club went viral over the summer -- but fans didn’t get to see the drama play out until season eight of the hit show premiered in November. Turns out Bailey wasn’t happy, and even questioned if she was still in love with her husband of five years.
4. Shannon Beador Takes on Husband David’s Mistress
First, the Orange County couple went public with David’s affair on the show. Then, they had to deal with the drama in the media. The Beadors came to ET to clear up reports that Shannon attacked her husband’s mistress as a USC football game this fall.
"I was shocked to see that she was there,” Shannon told us. “I'm not going to roll over.”
5. The Brooks Ayers Saga
Does Vicki Gunvalson’s ex have cancer? He says he does -- but Gunvalson’s co-stars questioned his diagnosis all season long, with Gunvalson eventually turning on Ayers.
“I think the whole thing is pretty disgusting," Gunvalson told Andy Cohen about the possibility that Ayers lied. "I don't understand it at all, I just think it's really odd and awkward."

6. Kim Richards
From her Beverly Hills Hotel arrest, to her wild behavior during an interview on Dr. Phil, her alleged shoplifting at Target, a stint in treatment, and reported erratic behavior at her daughter’s wedding, 2015 was definitely a difficult year for the Beverly Hills star. But, Kim’s sister Kyle tells ET the reality star is doing better -- and we’ll see her back on TV soon. She’s set to make guest appearances on the current season of RHOBH.
7. NeNe Leakes’ Surprise Exit -- and Surprise Return!
Bye, wig! NeNe Leakes announced over the summer that she was done with the franchise that made her a household name. Well, she was done… until this fall, when it leaked that she would make a few cameos on the new season of RHOA.
Leakes wasn’t the only Housewife to leave the franchise this year. New York lost Kristen Taekman and Heather Thomson, while Beverly Hills bid adieu to Brandi Glanville and Kim Richards.
