Bebé, bebé, bebé, ay! It was the girls of Mexico City whose turn it was to be less lonely last night — since the maravilloso Justin Bieber was in town. The frosty showman no doubt delighted his legion of south-of-the-border Beliebers with his roster of hits including "Never Say Never" and "Baby," busting out the dance moves and, of course, his killer smile. And the suave romancer was certainly given the star treatment upon his arrival, as he tweeted: "this hotel is the best...they surprised me with sand on my patio from cancun and said we wanted to make sure u enjoyed the beaches. #SWAAG", along with this pic. Not too shabby, Biebs.
