Watch: RHOA's Porsha Williams Files for Divorce From Simon Guobadia

The Real Housewives of Atlanta star is being sued by her estranged husband Simon Guobadia -- who she filed for divorce from in February following 15 months of marriage -- over comments she made on social media about erectile dysfunction, according to court documents obtained by TMZ Nov. 22.

In the filing, the Nigerian-born businessman alleged that Williams, 43, made "false and defamatory" comments about his genitalia in a series of Instagram posts, per the outlet.

And while Williams' Instagram Stories didn't specifically name Guobadia, the 60-year-old said that her messages subjected him to public ridicule due to her sharing them amid their ongoing divorce battle and presenting the information about erectile dysfunction as fact, according to TMZ.

E! News reached out to reps for Williams and Guobadia for comment but has not heard back.

Back in July, Williams -- who is mom to daughter Pilar, 4, from a previous relationship -- re-shared several posts to her Instagram Stories that provided information on how to "help with erectile dysfunction." Captioning each of her messages, the Bravo personality wrote, "#menshealthawareness."
