AdeleAdele has been ordered by doctors to stop singing and avoid talking for at least a month as she seeks to recover from laryngitis, according to reports.

The singer, whose '21' album returned to the top of the Billboard chart last week, was forced to cancel her North American tour earlier this month after her condition showed no sign of improvement.

She wrote on her official website at the time, "I'm really frustrated. I was hoping with a weeks rest I'd be better to sing again straight away. However there is absolutely nothing I can do but take the doctors advice and rest some more. I'm so sorry."
