Girls' night out — plus one! In The Real Housewives of Potomac's upcoming episode on Sunday, March 20, Karen Huger informs Ashley Darby that her husband, Michael Darby, should not have made a surprise appearance during the ladies' recent getaway trip to the Darbys' Bethany Beach place.

In Us Weekly's exclusive sneak peek, Karen tells Ashley that the trip to the latter's beach home was a success, with the exception of the final six hours, with Michael showing up unannounced on the last night. Several of the women, including Karen, had issues about a man staying in the same house as all the women.

However, Ashley is not convinced that Karen has a valid point and tells her: "You decided to all of a sudden have a tantrum like a 5-year-old, as [fellow Housewife] Charrisse [Jackson Jordan] did one night.”

Karen fires back: "I believe that Michael would not do that again. I think Michael is a mature man."

Watch the drama unfold in the video above.

The Real Housewives of Potomac airs on Bravo on Sundays at 9 p.m. ET.
