Meghan Trainor wrote a letter to fans explaining that "after a lot of reflection and some really tough conversations", she has decided to cancel her entire North American tour following the birth of her third child, Mikey, in January with husband Daryl Sabara. "Balancing the release of a new album, preparing for a nationwide tour, and welcoming our new baby girl to our growing family of five has just been more than I can take on right now, and I need to be home and present for each and all of them at this time," the singer, 32, wrote. "I know this will come as a disappointment to my fans, and I am so sorry to let you down. But I know this is the right decision for my family and me right now. I promise I'll be back soon." 📸 : Getty #MeghanTrainor
