A few days ago, rookie duo X-Cross released the MV for their debut single My Luv. Today, the boys have official started their promotional period for the song by debut on today's M! Countdown stage! This fresh-faced duo is a breath of fresh air to the stage, rocking out to their great mix of good looks, hot beats, and smooth choreography. Even though I find the current influx of newbies somewhat of a burden, these boys should definitely be an exception and should stay on your radars. Check out their debut performance below! http://www.youtube.com/watch?v=0A8hx-HeXIg
