She mentioned he was stressing her out." The eyewitness continued, "Everyone brought up 'Meri' and 'Robyn' as well and it wasn't in a positive light. You can tell they were all aggravated."

Meanwhile, the source noted that the hit TLC show was going in a different direction. The source said that Christine noted, "Maddie, I believe, was the one who said the show became 'volatile.'
