Mariah Carey's estranged husband Nick Cannon has signed on to host a new Lifestyles Of The Rich & Famous Tv special.

The actor/rapper-turned-Tv and radio personality will replace Brit Robin Leach, who has fronted the syndicated series since the 1980s.

Cannon's show has been picked up by executives at NBC and will focus the world's most extravagant people.

Unlike Leach, Cannon is one of them - he recently wore a pair of $2 million (Gbp1.3 million) shoes as the host of reality show America's Got Talent.
