Pop star, Lily Allen has blasted X Factor contestant Diana Vickers.

Lily was a hueg Ruth Lorenzo fan and when Ruth got booted out on Saturday night, Lily placed the blame squarely at Diana’s door.

"Ruth was my favourite – really Vickers should have gone. I felt the whole thing was a bit of a farce," Lily told Radio 1.

"When she didn’t sing on Mariah Carey week she should have had to come back the next week and sung a Mariah song as well as a Best Of British song.

"Then it would have been fair. I don’t think that Diana is very… good."

Allen continued that she thinks Vickers is better suited to the Eurovision song contest than the X Factor.

"Diana’s good enough for Eurovision!" she said. "I’m a nice person really, I just don’t like Diana Vickers!"
