Meghan Trainor has canceled her MTrain tour of North America because of a vocal cord hemorrhage. The "All About That Bass” singer announced the news via Instagram Tuesday, adding that she must undergo surgery to get it corrected.

"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,” Trainor, 21, wrote on Instagram. She also expressed her displeasure at the news and apologized to her fans.

“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," Trainor added. She told her Instagram followers that she loves touring and meeting new people every night and is “determined to do what it takes” to bounce back to normal. "I love you, and thank you for all of your understanding, love and support."

It's not the first time that the singer has canceled a tour. In July, Trainor was forced to cancel her tour because of the same reason - damaged vocal cords. Her MTrain Tour was expected to play through September. Her next stop was supposed to be at the Indiana State Fair on Aug. 15.

Trainor made sure to apologize to Charlie Puth and Life of Dillon, two opening acts on her tour. "I'm sorry to my amazing openers that we had to cut it short,” Trainor wrote on Instagram, adding that she will be “forever grateful” to them for their support.

The singer was active till Friday and even performed at Mix 104.1 Beach House Concert in Cape Cod, Massachusetts, E! News wrote. Fans who purchased tickets through advance bookings will be refunded.
