After Cryer won the Primetime Emmy Award for Outstanding Lead Actor in a Comedy Series September 23, he spoke to E! News about Cyrus' upcoming appearance. "[Missi] is just coming to L.A. to see what it's like to live out there. She stays with us for a few days and of course throws everything into disarray," he said. "[Miley] is beautiful and remarkable. You will enjoy her on the show!"
