The 'All About That Bass' hitmaker has suffered another vocal haemorrhage, forcing her to axe the remaining 15 dates of her North American tour as a result of the painful issue, which she will now undergo surgery for to fix "once and for all".

In a heartfelt message posted on Instagram, she wrote: "To all my fans - I was being careful and taking precautions, but I have hemorrhaged my vocal cord again. I got bronchitis & have been coughing a lot & that pushed it over the edge. Sadly, I will need to cancel the remainder of my tour and get surgery to finally fix this once and for all. I am devastated, scared, and so sorry. I LOVE touring and seeing your beautiful faces every night. I am determined to do what it takes to get better and come back around stronger than ever. I love you, and thank you for all of your understanding, love and support. (sic)"

The 21-year-old star cancelled a number of dates at the beginning of July after suffering a similar incident but was given the all-clear to continue performing a fortnight later.

However, she will now have her vocal cords operated on - as fellow musicians Sam Smith and Jess Glynne have also had this year - and as well as apologising to her fans Meghan has said sorry to her support acts Charlie Puth and Life of Dillon.

In another Instagram post, she wrote: "I'm sorry to my amazing openers that we had to cut it short.@charlieputh @lifeofdillon you guys put on great shows every night with big smiles and I will be forever grateful that you were a part of this experience, even though it was cut too soon. Thank you and your teams for everything (sic)."
