Lily Allen admits her fashion line isn`t `ground breaking`

The Smile hitmaker, who married builder Sam Cooper on Saturday, thinks that her designs are unlikely to change the face of fashion.

Lily said: 'Sarah and me work with a designer called Nadia Jones. We tell her what we would like and she does the sketches.

'We were inspired by vintage clothing - we're not doing anything ground breaking.'

Allen also said that working with her sister Sarah can be difficult at times.

The 26-year-old added to British More! magazine: 'It's challenging. It can be a struggle with family members. It's difficult not to be honest all the time. There's a lot of tongue biting.

'Crispin, who I work with, and I disagree about stuff, but I always hold back because we're not related. There's a lot more horrible stuff I could say. But yeah, with my sister, when she starts to irritate me I just want to pull a face. But I don't think everyone else in the office would like it very much.'
