Erika Jayne seems to be melting — or at least thawing — on , and ET has your exclusive first look! In ET's sneak peek, Erika shocks her castmates by engaging in conversation with her seemingly sworn enemy, Sutton Stracke, during the group's trip to Mexico. After Sutton announces to the women she has a date scheduled with a new guy after they get back from vacation, Erika starts asking questions about how she found this dude. «Did you meet him on the app?» she asks, with Sutton confirming she met the mystery man «on the Bumble.» The polite chat grabs Crystal Kung Minkoff's attention. She turns to Lisa Rinna and asks, «Can you believe them now?!» «They're sitting next to each other talking right now!» Lisa responds, stating the facts.«It's awesome,» Crystal remarks.
