Gabrielle Union and Dwyane Wade are springing into action to help the mother of the Alabama teen who recently died from suicide after he was mercilessly bullied for being gay.
Sources tell TMZ ... the actress and NBA star are part of a group of celebs -- which also includes Ludacris and Janelle Monae -- donating money to help cover Nigel Shelby's funeral. Nigel is the 15-year-old who took his own life nearly 2 weeks ago.
Nigel's mother, Camika, had said Nigel suffered from depression and struggled with his identity.
