Michael Phelps Shirtless In Brazil With A Skateboarding Tony Hawk [PHOTOS]
He claimed six medals in his final Olympics with four gold and two silvers to earn nomination for the 2013 Laureus World Sportsman of the Year Award.
The 27-year-old from Baltimore retired following London 2012 with a total of 22 Olympic medals, 18 of which are gold, to secure his status as one of the greatest athletes in history.
But the American faces stiff competition from Jamaican sprinter Usain Bolt, British distance runner Mo Farah, Argentinian footballer Lionel Messi, German Formula One driver Sebastian Vettel and British cyclist Bradley Wiggins to secure the prize.
Skateboarding legend Tony Hawk is also in Rio for the event, and showed off his major skills for some kids today.
