Porsha Stewart confused Underground Railroad of the Freedom Trail tour for a real train during the latest episode of "The Real Housewives of Atlanta."

"The Real Housewives of Atlanta" focused the spotlight on ghosts and a little bit of history lessons during an all-girls' trip to Savannah.

The wives, including Porsha Stewart, went on a Freedom Trail tour during the episode in order to study the historical aspects of Savannah. However, it seemed like understanding the Underground Railroad may have been a little too much of a challenge for Porsha Stewart.

After the tour guide showed the way to the First African Baptist Church and guided everyone's attention to the ventilation holes scattered on the floor wherein "people crawled under to escape slavery", Porsha Stewart became confused.

The 31-year-old then remarked that "There has to be an opening for the railroad."

The comment did not go unnoticed as fellow housewife Phaedra Parks was quick to explain that it was not in fact a train and only a euphemism.

Another reality television star, Kenya Moore, then commented, "It's almost hurtful to watch her be so dumb."

45-year-old NeNe Leakes just added "Ding. Dong," in response to Porsha Stewart's remark.

On the other hand, mortician Phaedra Parks was interested on the Hearse Ghost Tour they participated in later that night.

Recently-divorced Porsha Stewart was recently involved in an issue concerning her spot in "The Real Housewives of Atlanta." Rumors of her getting axed from the reality show after her divorce went through arose but was later denied.

Though she is not getting fired yet from the reality show, Porsha Stewart's future is still undetermined as of now since there have been no indications that she will be returning for the next season. 

Producers have refused to disclose any information for the next season of "The Real Housewives of Atlanta" though some sources claim that Porsha Stewart will be finishing this season and joining the cast in a season special after that.
