State Sen. Diane Savino is relieved she can finally talk openly about her romance with state Sen. Jeff Klein, sources say, after Page Six first reported on their relationship last month. She was quoted saying recently of dinners in Albany, “Sometimes it’ll just be me and Sen.

Klein’s spokesperson denied any secrecy: “The only thing Jeff Klein is trying to hide about his relationship is the fact that she makes him watch ‘Jerseylicious.’ “
