Mark Ronson has vowed never to make music with Lily Allen again.
The superproducer shot to fame after working on the Smile singer's 2006 debut album Alright, Still, but they fuelled rumours of a rift when Allen recorded her second CD without Ronson.
The pair dismissed claims they had fallen out, but Ronson insists they won't go back in the studio together.
He says, "I can't go back to working with Lily. There's been no falling out but our creative relationship has ended."
