It’s time to get familiar with The Real Housewives of Potomac.

Five of Bravo’s newest Housewives -- Gizelle Bryant, Karen Huber, Charrisse Jackson Jordan, Ashley Darby and Robyn Dixon -- joined ETonline for Housewives Happy Hour to celebrate their show’s Jan. 17 launch, and they’re already spilling major secrets! 

For one, they didn’t know they were going to be Real Housewives until long after they finished filming.

“The day you found out, we found out,” Robyn revealed. “I don’t think I could move for, like four hours … I was a little paralyzed.

“We were on a conference call, all of us,” Charrisse confessed. “The line went silent.”

Gizelle said their show didn’t even have a title until Bravo announced the series’ premiere date back in November.

“So, when we finally found out we were Real Housewives of Potomac, we were like, ‘O.M.G.,’” Gizelle cooed.

Even though it wasn’t filmed as Real Housewives, the show definitely lives up to what fans have come to expect from the franchise. Check out the video below to watch a game “Real Housewives Bingo or Hell No!” and find out just how similar Potomac will be to the other cities.

The ladies were happy to compare themselves to Housewives in those other cities, too. It turns out they’re a good mix of Beverly Hills and Atlanta.

Gizelle said she’s 90 percent Kyle Richards, and 10 percent NeNe Leakes; Karen is 100 percent Lisa Vanderpump; Charrisse said she’s a “schizophrenic” mix of Lisa Vanderpump and Kandi Burruss; Ashley called Porsha Williams her “spirit animal;” and Robyn said she mostly identifies with Kandi Burruss.

The ladies did not compare themselves to the short-lived Real Housewives of D.C., even though Potomac, Maryland, is only about 30 minutes outside the capitol city. When Bravo announced the new series, a lot of people asked, why not just revive the D.C. edition?

“Revival?” Gizelle scoffed. “Nuh-uh.”

“You know why?” Charisse asked. “‘Cause this group right here, we’re friends …  and the uniqueness, it’s not duplicated anywhere else but on The Real Housewives of Potomac. And it’s different from anything else you’ll ever see.”

Karen chimed in with that makes Potomac an ideal -- and unique -- backdrop for reality TV.

“Well, it’s culturally rich,” Karen started. “We have wonderful women -- obviously the six of us are quite fabulous -- and we’re not the only ones. Potomac is just a very, very hidden jewel, and now the world will know.”

“We are down-to-earth women, and everyone can relate to one of us,” Robyn added. “I mean, we have a range of ages. We span four decades: 20s, 30s, 40s, 50s … Although we are an all-African American cast … Potomac, itself, is a very diverse community, so you know, we’re not just what you see here. You’ll get to see a lot more.”

The Real Housewives of Potomac airs Sunday nights at 9 p.m. ET on Bravo, directly after The Real Housewives of Atlanta.
