Teddi Mellencamp Arroyave was hesitant to travel to Berlin, Germany with her co-stars during production on "The Real Housewives of Beverly Hills." Last night, fans learned why. As Mellencamp and her co-stars sat down for what was supposed to be a fun dinner at an exclusive restaurant in the city, erika girardi took aim at Mellencamp and called her out for accusing her of having "pretend amnesia."

As the rest of the women, including Kyle Richards, Dorit Kemsley, and Lisa Rinna, enjoyed a light-hearted conversation, Girardi confronted Mellencamp and slammed her for labeling her a "liar." As fans have seen during past episodes of the show, Mellencamp suggested Girardi was suffering from "pretend amnesia" when Girardi failed to acknowledge a conversation the two of them had about the tension between Lisa Vanderpump and Kemsley.

After spending a number of fun moments with her co-stars on a boat, the tension between Teddi Mellencamp and Erika Girardi boiled over, and in her blog, the newest member of the show spoke out about the awkward encounter with her co-star and their recurring issue.

Teddi Mellencamp enjoyed the majority of her time in Berlin

"This trip has been a lot of fun, and I’m glad [Erika Girardi] and I seem to be getting along like a panda with bamboo. But the long and short of it is that 'pretend amnesia' hasn’t been forgotten," she wrote. Continuing on to her readers, Mellencamp acknowledges Girardi's intense glare and says that she was about as comfortable with Girardi as "Friends" character Monica Geller would have been while "leaving Richard a voicemail."

Mellencamp then said that she and Girardi ultimately squashed their beef -- but only until the reunion.

Teddi Mellencamp will likely return to 'RHOBH'

Mellencamp, the daughter of rocker John Mellencamp, was brought to the cast of "The Real Housewives of Beverly Hills" last year for season eight and because she was involved in the majority of the cast's drama throughout season eight, it seems likely that she will be asked to return.

That said, fans will have to wait and see for sure when the cast returns to production for season nine later this year.

To see more of Teddi Mellencamp Arroyave and her co-stars, including Lisa Rinna, Kyle Richards, Dorit Kemsley, Lisa Vanderpump, Erika Girardi, and Camille Grammer, tune into new episodes of the eighth season of "The Real Housewives of Beverly Hills" on Tuesday nights at 9 p.m. on Bravo TV.
