Kristen, 35, was perhaps a little too honest after wine tasting!
When the sommelier poured her a glass of Merlot, she wasn't exactly thrilled.
"I think Merlot is the basic b***h of wine," she professed to the dismay of her costars.
The other women all shook their heads after the remark. Katie, 32, later said in her on-camera interview, "Kristen, we're wine tasting. It's supposed to be a classy, sort of elegant thing with your pinky up and this is the first winery of the day."
It didn't end there! Kristen then couldn't walk to the next winery. Once inside, she started "exhibiting weird behavior and rambling on about things," according to Stassi. "Crazy Kristen, she's not coming, she's here," the podcast host added.
