Stateside Adele fans are about to be bummed out. The British singer, whose sophomore set '21' has rung up several weeks at No. 1 -- has been forced to cancel the remaining nine dates of her sold-out, North American tour. An ongoing battle with laryngitis is the culprit.

The 23-year-old diva recently postponed five shows under doctor's orders when she was diagnosed with laryngitis. While resting in Los Angeles, Adele met with an Otolaryngology specialist who determined it was imperative that she take the next few weeks to recover with absolute voice rest.

Adele had planned to resume her tour on June 4 in San Francisco, Calif. before learning of her advanced
condition; now those plans have obviously been tabled.

Adele issued the following statement via her publicist: "I'm really frustrated. I was hoping with a week's rest I'd be better to sing again straight away. However there is absolutely nothing I can do but take the doctor’s advice and rest some more. I'm so sorry. See you soon. Love, Adele."

Plans to reschedule these canceled tour dates are being investigated; more information will be provided when available.

Overall, though, we can't blame Adele for canceling to avoid further damage to those powerful pipes of hers! That's the most important tool of her trade, so we can't fault her for following the advice of experts. If anything, the cancellations make us hungrier to see Adele when she is back at full strength.

Get well soon, Adele.
