Adele has cancelled two more concerts as she desperately battles a chest infection.

The Chasing Pavements hitmaker axed the start of her U.K. tour on Sunday (04Sep11) and also pulled a show on Monday (05Sep11) and a planned performance at the Mercury Prize ceremony on Tuesday (06Sep11).

She had hoped to be back on stage in Cardiff, Wales on Wednesday (07Sep11) but she is still not over her illness and has now axed that show and one in Blackpool, England on Thursday (08Sep11).

In a statement on her website, a spokesman writes, "It is with regret that due to continuing problems with a serious cold and chest infection, Adele has had to postpone her show tonight, Wednesday September 7th in Cardiff and the following date tomorrow, Thursday September 8th in Blackpool.

"She had cancelled her performance at The Mercury Awards (sic) last night in the hope she would be able to continue her live dates, but has been told by her doctors that she is still not well enough to perform... Adele is extremely sorry and apologises for any inconvenience caused and looks forward to seeing you all at the rescheduled shows."
