Cheryl married her 33-year-old boyfriend on the Caribbean island of Mustique with just four witnesses, including her mother Joan Tweedy and assistant Lily England.
The X Factor judge has a reported wealth of £16 million, though her new husband is said to be from a wealthy French family and wealthy in his own right.
Cheryl refused to sign a pre-nuptial agreement when she married ex-husband footballer Ashley Cole in 2006.
She said at the time: “I think that’s defeating the point… We’re getting married because we’re committing ourselves to each other to spend the rest of our lives together. No ifs and buts.”
“I think they (pre-nups) are disgusting. I could understand if you’re 93 and you’ve got billions of pounds and this 24-year-old wants to marry you in a month.”
“But we’re a work in progress, we’re going to build our married life together not thinking about if it ever ends.”
Following her Caribbean wedding to Jean-Bernard, friend close to the star said “She is a canny businesswoman but in matters of love, she believes the heart should rule the head to a certain extent.”
