Mariah Huq and Quad Webb-Lunceford can't seem to fix things on Bravo's hit reality show Married to Medicine. The former friends are at it again in this Sunday's upcoming episode, and Us Weekly has an exclusive first look.

After an explosive blow up at STK restaurant in Atlanta earlier in the season, which wasn't caught by the Bravo cameras, it seems these two ladies are still unable to reconcile things.

In the May 4 episode, the reality stars get into an altercation at costar Lisa Nicole's Women Empowerment Event in a back room she's dubbed "The Tranquility Room." In the clip, which is less than tranquil, Quad confronts the group and Mariah, exclaiming: "I'm not upset with Mariah, but there needs to be some truth told."

A heated Quad continues to Mariah, who accuses her of lying, "I'll up and throw you .. I'm telling you, you need to come clean."

Mariah's response? "I feel like way too much has happened," she tells the camera during a sit down interview, "and she's not going to come in here … with all her manipulations and BS."

Because cameras didn't catch exactly what went down back at STK, Mariah explains: "When I showed up at STK, Mrs. Quad had entourage and everybody knows she transforms to whoever is around, and I have no time for transformers."

Watch the clip above! Married to Medicine airs this Sunday at 10pm ET/PT on Bravo.
