Arduino Mega compatible Xbee Shield

Hello, I am currently using an Arduino Mega and I am looking at purchasing an XBee compatible shield for my robot. I was wondering if the one I found at Digikey would be compatible with it. I have asked the people there and they say that it will work for the Uno, but they were not sure if it will work with the Mega.
