Will Smith surprised hundreds of fans when he made an unannounced appearance at the Palms Casino Resort Ditch Fridays pool party late last week. As he enjoyed the sights and sounds of the hotel, the actor reunited with friend and former Fresh Prince costar, DJ Jazzy Jeff.

After not seeing each other for at least seven months, the duo quickly embraced each other with a hug and was even spotted dancing together. The party turned up a notch when the duo's famous hit, "Summertime," started to play. According to a source, Smith immediately jumped onto the stage to sing along. In fact, when "Jump On It" started playing later on in the DJ set, Smith tore off his shirt and got fans jumping in the crowd.
