Using xbee shield and motor shield together

Is there a way to use the Arduino xbee module and the arduino motor shield together?

Xbee shield: Shields — Arduino Official Store
Motor shield: Arduino Motor Shield Rev3 — Arduino Official Store

I really need to use them both. Are they stackable? (put one on the other on the arduino UNO)
If not, can I use a breadboard to use them both? How? Thank you
