highlight on mouse over

hi huys i got a question

I have a mc that has a mouse event that when its clicked it plays the animation within its timeline. Can i put a mouse over event on it so it has a yellow glow  when my mouse goes over it.

I am using flash cs5. AS3.

here is my code. its very simple.

import flash.display.Sprite;

clue_btn.buttonMode = true;
clue_btn.addEventListener(MouseEvent.CLICK, animate);

function animate(e:MouseEvent)

{
    this.addChild(e.currentTarget as Sprite); // puts the clicked object on the top layer
    e.currentTarget.play();
}

thanks
