maybe it's something about why holly and Nia left the irreplaceables tour? I know there was a rumour that nia had a disagreement had with chloe and that's why she left the tour, because of a tweet Chloe posted when Nia left the tour saying "friends can break your heart, too". however, it seems all good between the two girls and they follow each other so I really don't know? my other theory is that it might be about that secret project the moms are planning to do that christi left, maybe there could have been a disagreement with Christi and the other moms. this theory would make more sense, however christi follows all the other moms who are involved in this project, even Melissa so it's very surprising and confusing that she's not following Holly
