Kordell Stewart's ex-wife is close to being fired from her Real Housewives of Atlanta, Bravo Network reality show, according to several media reports.

Top Bravo execs reportedly are frustrated by some of Porsha Stewart's clumsy storylines and uninformed comments and now consider her "a mix of boring and annoying."

According to RadarOnline, Stewart further drew the ire of her cast members during a recent trip to Savannah, Ga. where they all visited a historical safehouse that was part of the underground railroad.

As they discussed the topic, Stewart naively blurts out "well, there has to be an opening for the railroad at some point because somebody is driving the train."

According to Radar, cast member Phaedra Parks tries to educate Stewart by informing her the railroad reference is simply a "euphemism" for the way some slaves were able to safely navigate their way to freedom.

Across social media, fans immediately slammed Stewart for her lack of knowledge about African American history, particularly given her status as the granddaughter of civil rights pioneer Hosea Williams.

"Shout to Porsha Stewart for literally thinking that the Underground Railroad was an actual subway system, with an actual train," tweeted one fan.

Kordell and Porsha Stewart recently finalized their bitter divorce, but not before airing out bitter laundry that included Porsha stewart claiming she only learned her husband planned to divorce her by reading Twitter. She has since regularly insinuated on her TV show she suspects her NFL ex husband might be gay.
