'I'm worried sick about my ex Simon . . . he's drained and exhausted' - Sinitta

Jonathan Gray

Pop star Sinitta has stripped off to recreate the classic image of Christine Keeler -- the woman at the centre of the Profumo affair.

Keeler had simultaneous affairs with UK war minister John Profumo and a Russian naval attache -- a political sex scandal which dogged Harold Macmillan's government.

Keeler was jailed for nine months in December 1963 for perjury.

Now 80s singer Sinitta has posed nude on the back of a chair imitating the portrait taken in 1963.

In a magazine interview, Sinitta said she was worried about the health of her former boyfriend Simon Cowell.

She said about the X Factor judge: "I know that he's exhausted. He doesn't normally start talking about it not happening again until the end of the series, so the fact he's doing it now is a little worrying.

"He's very drained and they haven't even started the live shows yet where it really kicks in.

"I try to persuade him to take a break, but he loves it so much.

"He's a workaholic, but he's so passionate and he won't stop you doing what you want to do. He's not as grumpy as he comes across -- he giggles all the time."

The 41-year-old helped Cowell out during the next stage of the music competition at his home, which will be aired next Saturday.

She added: "We fought a lot (when selecting his acts), but only because there were too many to choose from and I was right about Olly Murs last year. I'm pleased with who we picked."
