The 7th Annual Model America Championships in Las Vegas hosted nearly 100 of the country's hottest sports fitness models.  But it was local hometown stars Amanda Latona and Alex Castillo that took home overall honors.  Alex is a personal trainer originally from Cuban with limited modeling experience but recently moved to South Beach to ignited his career and be closer to his family.  Amanda is a convention spokesperson and model with extensive magazine and commercial background.  It was her second consecutive Model America victory and is seeking Hollywood representation to expand her opportunities.  The upcoming Model America Championships will once again be held at the Golden Nugget Hotel & Casino.  Competitors will be put through their runway paces in the Clubwear, Sportswear and Swimwear Rounds.
