The quirky teenager was given a green card through to the next round last week as she was diagnosed with laryngitis and the show's choreographer Brian Friedman today said, 'Di still couldn't sing yesterday. She just had no voice at all.'
Blimey, we're not sure producers will allow her to be off sick again this week. But how could they say no when they let her off before?
Doctors have made it clear that Diana faces damaging her voice permanently if she tries to sing before she's fully recovered.
After all the controversy surrounding Laura White's shock exit from the show last week we think there may be a national outcry on our hands if Diana gets another sick note.
What do you think?
