Leonardo DiCaprio flashed a wide grin as he casually strolled through the lobby of his hotel in Mexico yesterday. DiCaprio normally heads to the beach with a special lady — or ladies — to keep him company and this time was no different, he brought his mom along. His date-free status helped make his vacation you'd most like to crash over the long holiday weekend. Leo's on a short break after he wrapped up Inception last month and gearing up to start the promotional tour for his highly anticipated thriller Shutter Island that hits theaters in February.
