Cheryl Cole 'is a brunette again'

X Factor judge Cheryl Cole has ditched her flame-haired look after less than a month, a report claims.

The Girls Aloud singer recently unveiled red locks during a night out in London and later admitted that she had grown bored of her old image.

However, according to The Sun today, Cole has already returned to her natural brunette style for The X Factor's judges' homes stage, which she is currently filming in Morocco.

A source revealed: "It took a good three days to get her hair back to normal."

The latest X Factor round will see Cole picking the final three acts for her category, who will go on to star in the live shows later this year.
