A security officer who accompanied X Factor stars to Great Ormond Street hospital this week, has been diagnosed with swine fu and is terrified that he may have passed it on.

The 26 year old told The Sun:

“I was with the twins the most and Rachel gave me a big hug. I’m worried I’ve given them swine flu.

“I know it’s not my fault but I feel really bad because John and Edward were two of the nicest people I have met.”

A source said: “It’s very worrying news for the twins. If they’ve picked up swine flu they won’t be able to perform.”
