Osbourne struggling with grief over friend Winehouse

Kelly Osbourne hasn't left her apartment since returning from Amy Winehouse's funeral.

The 26-year-old star – who was a close friend of the 'Rehab' hitmaker, who was found dead at her home on July 23 – admitted after flying back to Los Angeles from London last week, she has found it difficult to move on and is afraid of crying "floods of tears" over the loss of her pal.
