The 'Set Fire to the Rain' star, who is rumoured to be recording the next James Bond theme song, will no longer appear in Plymouth on Sunday and Bournemouth on Monday due to poor health.
A message on the singer's website read: "It is with regret that due to a severe cold and chest infection, Adele has had to postpone the first two shows of her UK tour in Plymouth on Sunday September 4 and Bournemouth on Monday September 5 2011.
"The shows will be rescheduled at the earliest opportunity and all original tickets will remain valid. Refunds will be available from the point of purchase.
"We apologise for any inconvenience caused and look forward to seeing you all at the rescheduled shows."
Adele cancelled the remaining dates of her US tour in June after contracting laryngitis. She was banned from singing and talking by doctors and later announced new American dates across August and October.
She recently unveiled plans to project photos of her friends and fans on stage during her tour and asked people to send in photographs of themselves.
