Louis Walsh Stokes Cheryl Cole Feud
He claims she needs vocal lessons as he responds to her recent outburst...
The X Factor judge was left smarting recently when Chezza claimed in an interview that Louis had had "zero involvement" in the success of Girls Aloud when he was their manager.
He later declared that their "friendship is over", but has now used an interview in Heat magazine to retaliate in more detail - and he hasn't held back.
Louis said: "What is she peddling this time? Eyelashes or hairspray? It's definitely not her music! At least I am still on The X Factor and happy to be there. I'm a much better manager than she is a singer. She seems to be in the fashion business now, selling fake hair pieces, fake eyelashes, fake everything.
"Has anyone ever heard her sing live or a cappella? If she comes back on The X Factor, she needs to sing live this time. I don't know why she's started this war with me."
And Louis insisted that he had previously held Cheryl in high affection.
He continued: "I've always liked her - she's a very good looking girl, but obviously not the best singer in Girls Aloud. Nadine is - I always said that. Cheryl is a great clothes horse. Nice girl, but likes to get her own way.
"I've got two words to say: vocal lessons. When I write my book, I'll tell the real story of Cheryl."
