Cheryl Fernandez-Versini's husband is opening a London restaurant.

The 34-year-old entrepreneur, Jean-Bernard, wed the chart-topping singer last year, and is now racking the brain of his wife's fellow 'X Factor' judge Simon Cowell on where to open the upmarket eatery.

A source told The Sun newspaper: ''He is planning to open a restaurant this year in London, in either Mayfair or Soho. Simon has advised him about locations and suggested the West End because it will attract a really upmarket and A-list clientele.''

The move follows his successful pop-up nightclub and restaurant Cosy Box which he runs annually for the duration of Cannes Film Festival, where the couple met in May last year, before marrying just three months later.

Although the hunk is eager to create a rival to celebrity hot-spot Chiltern Firehouse which is one of the city's most popular restaurants for the stars, his 31-year-old lover has had other concerns recently after music manager Louis Walsh insulted the star's ability as a judge on 'X Factor'.

Hitting back at Louis on Twitter, she said: ''I am beginning to wonder if Louis has some kind of an obsession with me.

''I mean this is every year whether I am or am not a part of the show.

''.. and btw.. This is the same man asking me what he should say to contestants on our way to the stage bc ''he doesn't know'' (sic).''
