The Girls Aloud singer’s grueling dance routines on the band’s current UK
tour has aggravated the big toe injury she suffered while climbing Mount
Kilimanjaro for charity in February.

She said: “I’ve just been to see the doctor and he’s drilled a hole in my
nail to release the pressure. I feel quite disturbed.

“When I was training for the climb, my boots were too tight, which put
pressure on my toe and the nail went black.

“It was growing off, but now, with all the dancing we do in high heels for
the tour, it’s built up again and it’s hurting like hell every night. The
doctor said I was brave, though!”

Cheryl - was heavily criticized after being found guilty of assaulting a
nightclub toilet attendant in 2003 - is also shocked at how she has
transformed into the “Nation’s Sweetheart” after winning over the British
public as a judge on UK TV talent show ‘The X Factor’ last year.

The 25-year-old brunette beauty added to Britain’s Hello! magazine: “I do
struggle with that - the Nation’s Sweetheart thing - because I don’t really
get it. I’m just myself.

“It’s lovely, though. I can think of worse things to be called - and I have
been! I’ve gone from one extreme to the other - I was a bit of a pantomime
villain before. But I can feel the difference in people’s attitude towards
me wherever I go, I really can. I can feel the love and that’s really nice.”
