London, Aug 18 - English singer Robbie Williams fears that he has contracted swine flu.

The 'Angels' hitmaker posted on his blog that he is seeking medical advice to confirm whether he has it or not, reported contactmusic.com. 'Off to the doctors to confirm if I have pig (swine flu) or not,' he wrote.

His spokesperson insists he just has a cold.

'He was just being ultra careful by going to the doctor. He was shooting his video for the new single 'Bodies' last week and picked up a cold on the set,' said the spokesperson.
