Cheryl Fernandez-Versini is planning to open a restaurant in London.

The 'Crazy Stupid Love' singer - who revealed on Monday (14.07.14) that she'd married her boyfriend of three months Jean-Bernard Fernandez-Versini in a secret ceremony last week - is said to be helping her new husband decide on a location to open one of his luxury Cosy Box pop-up restaurants.

A source explained: ''Cheryl's been really involved in helping JB find the perfect spot for his first restaurant here. They're considering trending London areas like Shoreditch, Notting Hill, Soho and Dalston.

''JB is very well travelled but Cheryl is loving getting to show him the ins-and-outs of London.''

Jean-Bernard - who launched Cosy Box in 2008 - is said to be keen to get his new wife, 31, involved in all aspects of the business.

The source added to The Sun newspaper: ''When the restaurant opens, she wants to get involved and JB's joked that he'll put her to work in the kitchen.''

Meanwhile, it's been reported that prior to their secret wedding ceremony on a beach on the Caribbean island of Mustique, Cheryl refused to sign a prenuptial agreement to protect her £16 million fortune.

The brunette beauty refused to sign one before marrying her ex-husband - former England soccer star Ashley Cole - in 2006 as she claimed the idea of a pre-nup was ''disgusting''.

A source close to Cheryl's family told the Daily Mirror newspaper: ''She is a canny businesswoman but in matters of love, she believes the heart should rule the head to a certain extent.''
