Later that night, after escaping, Lovato brought DNCE and Jonas on stage during her performance at L.A. Live to sing their song, "Toothbrush."
Like Jonas and Lovato, the Jenner sisters have also had a recent brush with being trapped in an elevator. Their ordeal happened earlier this month, during New York Fashion Week, when they were stuck along with pals Hailey Baldwin and Jordyn Woods.
That scenario almost ended badly when Kylie realized Kendall had eaten a granola bar, which turned out to be all the food they had. Fortunately, the women were rescued by the fire department before they had to resort to a Hunger Games-style battle for survival.
