Sammy Sosa – the Light Bright edition – was spotted at Club Play in Miami for Pitbull’s 30th birthday shindig.

Yeah… we’re starting to think it’s a lot more than a “side effect to a skin cream.” Either a) Sammy’s got some illness that’s gonna make us feel bad for talking about him; or b) the skin cream was a bleaching cream, period point blank.

Other notables at Pitbull’s party: Fubu’s Daymond John, Rocsi Diaz, Jon Secada… We would have expected a little more A/B-list action going on.
