Actress Jessica Alba says she can relate to feelings of self doubt and being judged.

The `Sin City: A Dame to Kill For` actress has recently opened up about her insecurities as a young woman and has now teamed up with German consumer product Braun's 'Break Free' campaign in a bid to spread positivity amongst women, reports femalefirst.co.uk.

She said of her involvement: ''I completely relate to feelings of self-doubt and feeling judged but, happily, I also know personally how wonderfully empowering female positive reinforcement is.

''I'm encouraging women to say, share and show their support to female friends, family, colleagues - sisters everywhere.`

''Let's give each other the confidence to break free from self-doubt and all walk that little bit taller. Think of a woman you admire today and tell her,` she added.

The `Break Free` campaign follows research that revealed 91 per cent of women feel judged in everyday scenarios and 85 per cent lack the faith that other women admire them.
