On Sunday’s broadcast of Bravo’s “Watch What Happens Live,” “Real Housewives of Atlanta” star Porsha Stewart finally got a chance to comment on her “Underground Railroad” embarrassment.

“When I watched that, I realized that was another ‘Porsha moment”…a little airy, there, just a brain lapse,” she told host Andy Cohen.

The granddaughter of civil rights leader Hosea Williams said she didn’t feel the need to address her other “Porsha moment” — referring to the number of days in a year as “265.” But in believing the Underground Railroad was an actual train, she said, “I felt like I definitely needed to correct that.”

Porsha said it’s “a very sensitive topic for me,” and that she “went back and read up on the underground railroad…because I do want to represent that part of my life and legacy better than I did.”

Later in the broadcast, Porsha answered a fan-tweeted question regarding rumors that her ex Kordell Stewart is now dating “Braxton Family Values” star Towanda Braxton.

“I think that’s great, I love Towanda,” Porsha said. “I’ve watched her show and if that works for him then I’m happy.
