Sofia Richie has reportedly unfollowed family friends Lisa Rinna and the Hamlin sisters over Amelia's "betrayal".
Girl code seemingly went out the window when Amelia, 19, reportedly struck up a romance with Sofia's ex Scott Disick, 37, in recent weeks.
Claims emerged the model, 22, felt "betrayed" by her so-called family friends and as a result wiped them from her social media profile.
Sofia was believed to be devastated when her on/off three-year romance with Scott came to an end earlier this year.
A source told MailOnline: "Sophia has unfollowed Lisa Rinna and the Hamlin sisters on Instagram.

They appeared to be more than friends when they walked along the beach just 24 hours after having dinner together.
Sofia and Amelia were once friends as they kept to the same social circles within Hollywood.
And it seems Sofia isn't the only one who opposes the match.
Amelia's mum Lisa reportedly has her concerns about her daughter dating a father-of-three with "baggage".
She had an on/off relationship with Scott
It's further claimed the mum will not acknowledge the romance for now.
A source told The Sun : "Lisa isn’t going to acknowledge this publicly for now because she’s still trying to wrap her head around it and thinks this is a phase.
"But when she does speak about it she’ll keep her cool but really, she’s worried… That’s her youngest kid.
"She really does like Scott but both her and Harry don’t want someone that age with so much baggage to be with their baby girl, especially given Amelia’s own mental health issues."
