Though the tragic death of Michael Jackson was over two months ago, the entertainer's birthday was celebrated with light hearts across America. In Las Vegas, the King of Pop was posthumously awarded a star on the Palms Casino Resort's Walk of Fame. On the day Jackson would have turned 51, director Spike Lee threw a party in Brooklyn's Prospect Park, where fans turned out in the thousands despite pouring rain. In Mexico, fans hosted their own massive celebration, gathering in record numbers to honor the 'Thriller' singer with a mass dance extravaganza. Watch:
