Lily Allen's father Keith has said being a pop star makes her "very depressed".

The actor's comments follow a blog posting in which Lily said she was "fat, ugly and s**tter" than Amy Winehouse.

He explained: "She hasn't stopped for a year and a half. I remember meeting Robbie Williams and thinking him the saddest person I had ever met.

"I thought, 'Why doesn't he just give it up?' I haven't said that to Lily, yet, but I will."
