Meghan Trainor may be a Grammy-winning artist, but even she has her slip-ups from time to time. During a performance of her hit track "Me Too" on The Tonight Show Starring Jimmy Fallon on Thursday, the singer took a hard tumble when her high heels proved they were not made for walking. Even though she tried to steady herself with her microphone (skip to 3:44), she ended up falling on her back, but the host wasn't going to leave her hanging. Like a true gentleman, Jimmy joined her by lying down on the stage floor. Meghan had the last laugh, though, when she took to Twitter afterwards, writing, "Might have fell down... but I KILLLED that sh*t hahaha #keepinitreal thank you @fallontonight." Way to handle it like a pro!
