How to use jquery next() to select next div by class

I'm fairly new to jquery and struggling with something that should be fairly simple. I want to select the previous and next div with class "MenuItem" from the div with class "MenuItemSelected".

HTML

<div id="MenuContainer" class="MenuContainer">
    <div id="MainMenu" class="MainMenu">
        <div class="MenuItem">
            <div class="MenuItemText">Menu Item #1</div>
            <div class="MenuItemImage">images/test1.jpg</div>
        </div>    
        <div class="MenuDividerContainer">
            <div class="MenuDivider"></div>
        </div>
        <div class="MenuItem MenuItemSelected">
            <div class="MenuItemText">Menu Item #2</div>
            <div class="MenuItemImage">images/test2.jpg</div>
        </div>
        <div class="MenuDividerContainer">
            <div class="MenuDivider"></div>
        </div>
        <div class="MenuItem">
            <div class="MenuItemText">Menu Item #3</div>
            <div class="MenuItemImage">images/test3.jpg</div>
        </div>
    </div><!--/ .MainMenu -->
</div><!--/ .MenuContainer -->

Here is the jquery for next that I thought should have worked.

$('div.MenuItemSelected').next('.MenuItem');

I also tried

$('div.MenuItemSelected').nextAll('.MenuItem');

The only thing i could get to work is

$('div.MenuItemSelected').next().next();

That seems hokey, any ideas?
