Meghan Trainor will have vocal surgery.

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).''
