Meghan Trainor still doesn't care what the haters have to say. The pop star, 31, clapped back at people who have criticized her weight in a teaser of her unreleased song "Still Don't Care" via Instagram on Monday, November 3. "You say I'm doing too much, and you're probably right / That's the same s*** I've heard my whole life," Trainor lip-synched in a video as she danced to the music.
