It appears that one of the most famous celeb friend duos have officially called it quits on their relationship. 

5 Things To Know About Cara Delevingne

According to The Daily Mail, things have officially cooled between model Kate Moss and her former pal, Paper Towns star Cara Delevingne, after Moss became ticked that Delevingne quit her modeling agency to pursue her career as an actress, and also disliked an argument the 22 year old previously got into with her other pal, Naomi Campbell, earlier this year. 

"Kate has blacklisted Cara now. It's very unfortunate and hopefully might be a temporary thing, but they're definitely not friends at the moment."

"Kate wasn't happy with Cara's clash with Naomi and felt she should have treated her with more respect," the source added. 

Earlier this year, Delevingne and Campbell reportedly got into a nasty fight over Cara's allegedly 'disrecpeting' their mutual friend Rihanna, and now Moss appears to be siding with Campbell in the situation. 

"Naomi accused Cara of 'disprespecting' Rihanna and started yelling, before Naomi pished Cara, who pushed back. Cara pulled Naomi's weave, but it didn't come off," sources claimed at the time. 

Campbell's reps denied the altercation took place. 

As for the issue with Moss being upset her protégé left her agency, sources told the website that she was 'unhappy' Delevingne had quit her agency, and that while she was fully supportive of her acting career, she was 'annoyed with some of her behavior.'
