PUMA Motorsport hosted a party in Las Vegas last night to celebrate the Fall 2012 launch of its partnership with Mercedes Petronas GP and BMW Racing, adding to the brand’s already existing motorsport portfolio that includes Ferrari and Ducati. The collaborative project will include a collection of apparel and footwear, samples of which were on display. The exclusive event, dubbed the Puma Chop Shop and held in an actual motorsport garage, drew a crowd of hundreds to see performances by Meek Mill, Santigold, Diplo, Josh Madden and Luke Christopher. Celebrity guests in the house included actress Gabrielle Union and True Blood‘s Ryan Kwanten. Check out images from the celebration in the gallery following the click.
