The escort grandmother of X Factor reject Katie Waissel claims the pop wannabe has ‘ruined’ her career.

Sheila Vogel-Coupe, 82, who also starred in a hardcore pornographic film, said it was Katie who had damaged her work, rather than the reverse.

She also denied she was a prostitute during an interview on ITV1’s This Morning – but admitted charging for ‘other things’.

Sheila’s escort work – and porn film past – emerged as Katie was battling it out on the live X Factor shows.

She also posed in lingerie for a magazine on the back of her notoriety.

Shelia blamed Katie’s quest for musical success for putting her escort work in the public eye.

“This all started when Katie joined The X Factor,” she said. “She has ruined my career. Yes, I’m afraid she has.”

She added that her ‘private life’ had nothing to do with the rest of the family.

Explaining her work, she said: “I’m not a prostitute, I’m an escort… I go out with gentlemen and I attend the opera with them, I go out for dinner with them, but I’m not a prostitute.

“I do charge them yes, for my time. During my time we may just sit and talk, we may go out for dinner, we may go to the cinema, and we might do other things, yes.”

Sheila said the revelations had split her family apart, although she was still in contact with one of her daughters and a grandson.
