Don't mess with the professor!

Dr. Wendy Osefo made her debut on The Real Housewives of Potomac during season five, but she's coming out hard in her sophomore season.

In this season's trailer, Gizelle Bryant brings up allegations that Wendy's husband, Eddie Osefo, may have cheated on the reality star.

"Don't you play with my husband's name. So when she crossed that line, it was like... cut these cameras. I don't care, it's game time. I cleared that right on up. She got dragged once and then she got dragged again, and then I came in and I brought the tractor trailer and I dragged her again, so... if that's what you want to do, let's do it," Osefo said.

The doc also claims to meet an entirely new side of Gizelle in the new season.

"She didn't necessarily show me anything my first season to be... a horrible person. Second season... I'm like... everything everyone said about you is true. Both on... and off camera."

The Real Housewives of Potomac premieres Sunday night on Bravo.
