British singer Lily Allen has snubbed her producer Mark Ronson by skipping a gig where she was due to perform - to party with friends. The Smile star - who is dating Chemical Brothers star Ed Simons - was billed to appear at a north London venue on Wednesday (24Oct07) with the rising music producer but pulled out at the last minute. She was then spotted enjoying a night out with pals on the other side of the city. Ronson - who produced some of Allen's songs on her debut album Alright, Still - told the crowd, "My friend Lily was supposed to be here but she cancelled last minute."
