Rihanna is devastated after being forced to cancel another concert.

Having only kicked off her new Diamonds World Tour on Friday night, she came down with a severe combination of laryngitis and flu immediately after her debut show and pulled out of her performance in Baltimore on Tuesday night despite taking three days off to get better.

The singer is said to be extremely disappointed that she has only been able to perform one show to date, taking to Twitter saying: 'BOSTON this is the hardest thing for me to deal with! I feel like we've been waiting on this day forever, and I'm hurt that I let you down. I hate disappointing people that never ever let me down!! I'm so embarrassed about this! Thank you for your prayers and well wishes! #DWT'

Live Nation previously said the singer was under doctor's orders to rest, saying: 'Unfortunately, following her sold out concert on Friday, Rihanna has contracted laryngitis and per doctor's instruction is unable to perform this evening.'

RiRi is still currently scheduled to take to the stage in Philadelphia on Thursday, and while it's a long while off from her Dublin appearances, let's hope she kicks any sickness to the curb before June rolls around, lest we have to deal with thousands of squawking upset teens.
