Possible to reverse a css animation on class removal?

I would have the #item start out hidden with the reverse animation by default. Then add the class to give it the animation and show the #item. http://jsfiddle.net/bmh5g/12/

$('#trigger').on({
  mouseenter: function() {
    $('#item').show();
    $('#item').addClass('flipped');
  },
  mouseleave: function() {
    $('#item').removeClass('flipped');
  }
});

#trigger {
  position: relative;
  display: inline-block;
  padding: 5px 10px;
  margin: 0 0 10px 0;
  background: teal;
  color: white;
  font-family: sans-serif;
}

#item {
  position: relative;
  height: 100px;
  width: 100px;
  background: red;
  display: none;
  -webkit-transform: perspective(350px) rotateX(-90deg);
  transform: perspective(350px) rotateX(-90deg);
  -webkit-transform-origin: 50% 0%;
  transform-origin: 50% 0%;
  animation: flipperUp 0.7s;
  animation-fill-mode: forwards;
  -webkit-animation: flipperUp 0.7s;
  -webkit-animation-fill-mode: forwards;
}

#item.flipped {
  animation: flipper 0.7s;
  animation-fill-mode: forwards;
  -webkit-animation: flipper 0.7s;
  -webkit-animation-fill-mode: forwards;
}

@keyframes flipper {
  0% {
    transform: perspective(350px) rotateX(-90deg);
  }
  33% {
    transform: perspective(350px) rotateX(0deg);
  }
  66% {
    transform: perspective(350px) rotateX(10deg);
  }
  100% {
    transform: perspective(350px) rotateX(0deg);
  }
}

@-webkit-keyframes flipper {
  0% {
    -webkit-transform: perspective(350px) rotateX(-90deg);
  }
  33% {
    -webkit-transform: perspective(350px) rotateX(0deg);
  }
  66% {
    -webkit-transform: perspective(350px) rotateX(10deg);
  }
  100% {
    -webkit-transform: perspective(350px) rotateX(0deg);
  }
}

@keyframes flipperUp {
  0% {
    transform: perspective(350px) rotateX(0deg);
  }
  33% {
    transform: perspective(350px) rotateX(10deg);
  }
  66% {
    transform: perspective(350px) rotateX(0deg);
  }
  100% {
    transform: perspective(350px) rotateX(-90deg);
  }
}

@-webkit-keyframes flipperUp {
  0% {
    -webkit-transform: perspective(350px) rotateX(0deg);
  }
  33% {
    -webkit-transform: perspective(350px) rotateX(10deg);
  }
  66% {
    -webkit-transform: perspective(350px) rotateX(0deg);
  }
  100% {
    -webkit-transform: perspective(350px) rotateX(-90deg);
  }
}
