The unnamed rich man is looking for someone to test his future wife's loyalty before he walks down the aisle with her.

Aaron Harpin, founder of HushHush.com, said: ''The concept of 'gold diggers' isn't new. Indeed, it's something that the rich and famous have long had to deal with. However, rarely do we see people tackling it in such a direct way. Obviously we're hoping that if and when the right person is found for the unusual role, they won't be able to make our client's fiancée sway from him; no one wants to see couples break up, especially when they're set to get married.''
