Kiss rocker Gene Simmons is launching a new reality Tv show called Coliseum which will pit bands against each other like Roman gladiators.

Simmons will take on a judging role, acting as a 'Rock Caesar' deciding the fate of the competing acts.

The rocker says in a statement: "Coliseum is a no-holds-barred competition show between musical gladiators in the arena fighting to survive, fighting to be the champion, fighting to curry the favour of Rock Caesar."

The rocker-turned-reality-star also appeared in previous reality Tv shows including Gene Simmons Family Jewels and Gene Simmons' Rock School.
