Adele has cancelled more dates on her UK tour due to illness.

The Someone Like You singer was due to perform at Wolverhampton's Civic Hall on 10 and 11 September, but pulled out of both shows just days after cancelling gigs in Cardiff and Blackpool, which were due to take place on 7 and 8 September. She had earlier postponed shows in Plymouth and Bournemouth.

A statement on Adele's website reads: "It is with regret that due to continuing problems with a serious cold and chest infection, Adele has had to postpone her shows this weekend in Wolverhampton.

“Her doctors have insisted she recovers fully before returning to the tour. 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. Sincerest apologises for any inconvenience caused."

Earlier in the week the Rolling In The Deep chart-topper had posted her own message on the website apologising to her Cardiff fans.

She wrote: "I'm still not well enough. I woke up feeling a bit better but not by a lot, but decided to head towards Cardiff anyway in the hope I'd be able to sing tonight - halfway there I realised it was unrealistic. I apologise profusely, I know many of you would have travelled to Cardiff today for the show. I'm so so sorry!"

Adele briefly appeared at the Mercury Music Prize annoncement on 6 September. She had been due to perform but instead the sickly star made a short speech; the award was won by P J Harvey.

On a brighter note, her 21 album is on track to sell 13 million by the end of the year, [uuid=20869b9f-2e2d-4e8d-9865-0c0a81080e88]dwarfing the number sold by last year’s highest-seller[/uuid], Eminem’s Recovery.
