Friends of Cara Delevingne say she is in a poor position, dealing with difficulties beyond substance misuse, and they are getting increasingly desperate to help her.
This week, Margot Robbie, one of the model's closest pals, was seen leaving Cara's L.A. home in tears.
TMZ has been informed by reliable sources that Margot had excellent reason to let her feelings out that day. Cara has reportedly been having problems for some time now; her loved ones initially thought it was with her mental health, but they now think she needs to go to rehab as well.
We've heard that Margot and some other friends are pushing hard for Cara to enter a treatment centre ASAP, where she may receive both mental health counselling and addiction recovery services.
You may remember that Cara and Margot took a trip in August to celebrate Cara's 30th birthday by visiting Spain. Since returning from that trip, Cara has displayed increasingly unpredictable behaviour in public.
She boarded one of Jay-private Z's jets from Los Angeles last week looking dishevelled and disoriented. She got off the plane 45 minutes later, after it had failed to take off.
Margot was late for her own NYFW event because she decided to see Cara instead. In the end, she was unable to reach New York City.
Despite the fact that Cara hasn't come out and said no to therapy, we've heard that she's hesitating and that her problems are just becoming worse.
