“Jersey Shore” creator Anthony Beltempo is developing a reality show starring Long Island mob-related rapper Tony Testa and his family. Sources close to Testa, a nephew of jailed mob boss Joseph Carmine Testa, say Beltempo “is working on a show around Testa and his family on Long Island. They are a wild bunch.” The family members all live in houses on a cul-de-sac in Commack. Beltempo couldn’t be reached. A rep for Testa, who owns three tanning salons and is working on a rap album, said, “They have been shooting him with his family.”
