Lily Allen is undergoing therapy to reassure her she is not a ''bad person''.

The 'Hard Out Here' singer, who has children Ethel, two, and Marnie, 15 months, with husband Sam Cooper, claims speaking to a therapist helps her with ''complicated relationships'' and admits the busier she is, the more she struggles.

She told ''I had a session last week for the first time in a year.

''It helps get my relationships in order. I have quite a lot of complicated relationships.

''Lots of weird co-dependencies. And when I'm busy, things happen. I get quite confused about my place. I sometimes need someone to tell me I'm not a bad person.''

The 29-year-old singer - who previously checked into The Priory clinic after suffering depression - admitted she has had issues with troublesome friends, and the pressure of relaunching her career after a four-year break ''got a bit much'', prompting her to seek help.

She continued: ''I try to mother everyone. And trying to do that while relaunching a pop career and looking after two children got a bit much for a minute. I'd been so manic.''

Lily lost her godfather, musician Roger Pomphrey to liver cancer in January, which inspired her to quit smoking and she is hoping never to go back to the deadly habit.

She explains: ''I looked at my cigarette and thought, 'What am I doing?' I want to do it as best I can. I don't want to be a smoky-cokey mum. I hope I can keep it up - it just kills you.''

The 'Not Fair' star sees drugs, alcohol and cigarettes as ''distractions'' and claims they don't often agree with her and the party lifestyle isn't always as glamorous as it appears.

She added: ''No one would ever say I'm at my best when I'm really high.

''It's never as glamorous as it looks. It's fun, until 2am.

''I never once woke up and thought, 'God, I had such a good chat with that person at 5am - I'm so glad I had unprotected sex with them.''
