"James wants Lily to take on a bigger part but she is happy with a cameo," the Sun quoted a source as saying. Meanwhile, even though Allen is great friends with Horne and Corden, she has not been able to impress The Kooks front man Luke Pritchard, who is still immune to her charms.
The Smile singer had badmouthed him on her MySpace page last year, but she is now trying to get back in his good books by covering the band's hit Naive. But Pritchard, who had been friends with Allen at school when they were 13-years-old, is not falling for any of it.
"I find it funny she's a musician now because she never used to be into music at school," Pritchard said. "I don't really like her music all that much," he added.
