Android Create Drawable XML with Image rounded top corners

I'm trying to create an Android XML Drawable that I can use as the background for one of my LinearLayouts. I need the background to have an image, with the top left and top right corners rounded with a 10dp radius. I've been trying with the code below, but just can not seem to get it working. Is this possible? Any help is greatly appreciated!!

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://ift.tt/nIICcg">
<item>
    <shape android:shape="rectangle">            
        <corners android:topLeftRadius="10dp"
                 android:topRightRadius="10dp">                
        </corners>
    </shape>
</item>
<item>
    <bitmap android:src="@drawable/bg_navbar_blur" />
</item>
