Lily Allen is sick of pop stars lecturing their fans.

The 'Not Fair' singer is currently taking a break from the music industry to be a mother to her two-month-old daughter Ethel - her child with husband Sam Cooper - but it seems she isn't impressed with the rhetoric of the people who have taken her place.

She wrote on her twitter page: "Sorry are motivational speech making skills a pre requisite for all popstars these days , seriously , f**k off. (sic)"

Although Lily doesn't say which musicians are angering her, she did praise one of her peers via the micro-blogging site.

The 26-year-old brunette is a fan of new artist Lana Del Rey and has singled out one of her tracks for praise.

She tweeted: "i must say i'm rather fond of Miss Del Ray's "off to the races" (sic)"

Since marrying and starting a family, Lily now spends most of her time in her country house in Gloucestershire and stays out of the limelight.
