Sadie Frost Worried About Her Troubled Friend Kate Moss

British fashion designer and supermodel Kate Moss' best pal, Sadie Frost, is reportedly so worried about Moss that she has cancelled her family plans to spend time with her kids to be with the troubled model, who is said to be having a wild time in Marbella, Spain.

"Sadie is worried Kate's just having a kneejerk reaction to losing Pete. She's been on the phone to her daily, counseling her and telling her to be careful," The Daily Mail quoted a source as saying.

"Sadie believes this is a crucial turning point for Kate and that this time she may actually kick the Pete habit but she needs to be very careful."

Kate dumped the Babyshambles singer last month after finding out he had a "fling" with another woman.
