We had the best time in our hometown this past weekend!
To celebrate, we hosted an intimate party with some of our family and friends for the release of The Boy With Pink Hair.
The cocktail party was held at the Eden Roc Renaissance in Miami Beach and a special thanks to the lovely Marysol Patton from The Patton Group and to Martini & Rossi Moscato d'Asti for helping us make the night a success.
So wonderful to spend time again in the M.I.A.!
