Kevin "Blue" Hampton -- the runner-up on season 2 of MTV's "From G's to Gents" -- just come together with his father and sister after more than 20 years apart ... and, ironically, it's all thanks to the "G's" reunion show.
Last time he saw his dad when he was two-years-old -- when his mother left his father to move to Los Angeles with him in tow.
Fast ahead to a few months ago, when Blue says he received a My-Space message from a woman who had just seen the "G's" reunion show and claimed to be his older sister. Turns out his sis recognized their mother -- who was in the audience during the reunion show.
