Meghan Trainor has been given the green light for her tour after figuring in a medical emergency. On Tuesday, she resumed the dates of her tour starting in St. Louis, Missouri.

According to Billboard, the singer was given the okay by her doctors on Monday.

She immediately took to Instagram to share the good news to her fans who have been affected by the postponement of some tour dates.

"Great news!!!" she posted on Instagram.

"Doctor says I'm OK to sing!! So happy!!" she added.

Just a few hours later, she then posted on Instagram again that she's already on St. Louis where she was scheduled to perform on Tuesday.

"Riding around St. Louis airport feeling cool," she wrote on a video of her riding a Mohawk.

It was on the first week of July when the singer sadly announced the cancellation of the first few weeks of her "MTrain Tour" citing vocal hemorrhage as the reason.

She had to cancel then the Meghan Trainor tour dates on Atlantic City, New Jersey and Mohegan Sun, Connecticut as well as some concerts in Michigan and Chicago.

"I'm so sorry Megatronz please forgive me," she explained on Instagram then.

"I will never speak and completely heal as soon as possible so I can show you how hard we've been working on this," she also said.

"I have never missed a tour date before so this is killing me," the picture attached to the post said.

"I am truly sorry to everyone who has bought tickets and made travel plans," the text picture also read.

After St. Louis, the "All That Bass" singer will next appear on San Antonio, Texas on Thursday and Denver, Colorado on Saturday, according to her website. No word yet if the other Meghan Trainor tour dates that were cancelled earlier will be rescheduled as soon as possible.
