Rocker Jon Bon Jovi proved he really is a super-nice guy after he called for fairer wages for New Yorkers during a surprise appearance at a rally by the city's Governor Andrew Cuomo on Thursday.

The politician was campaigning to promote a new wage board designed to increase pay for fast food staff in the Big Apple, and the Bon Jovi star, who is performing in the UAE later this year, gave a speech backing the project.

The Livin' on a Prayer hitmaker told delegates: "Raising wages is about fairness. It's about giving more hard working New Yorkers more of a shot at making ends meet. The economy has come back, but not for all Americans. This issue is about paying people a living wage, while addressing the real cost of living."

Officials on the New York wage board are expected to announce their recommendations next month.
