Vocal superstar Adele has been forced to cancel her entire U.S. tour due to ongoing problems with her throat and voice. 

In an emotional blog post (October 4), the 'Chasing Pavements' hitmaker explained to her American fans that she is "heartbroken and worried" to have to cut the string of ten dates and wanted to let them know the full extent of the situation:

"I have never been able to fully recover from any of the problems that I've had and then continue to rest even once im recovered, because of my touring commitments. I've been offered the chance to not tour at all to save anything like this from happening again, but I simply hate letting you down."

"If I continue to pick up everything before I have properly conquered these problems and nipped them in the bud, I will be totally and utterly fucked. Singing is literally my life, it's my hobbie, my love, my freedom and now my job. I have absolutely no choice but to recuperate properly and fully, or I risk damaging my voice forever."

She went on to say that she's "devastated and annoyed" at having to bow out of the tour and added, "I apologise from the bottom of my heart, sincerely i do."

She was due to begin the run of dates on Friday, October 7 in New Jersey. Watch her recently released video for 'Someone Like You' here:
