The 31-year-old singer recently married her French boyfriend of three months in a secret ceremony, and later confirmed that she has officially taken on his surname, reported Daily Mirror.
Franck Twister, who is a business partner and close friend of Jean-Bernard, said, "They became inseparable, laughing and joking away like little children.
"She has a very strong accent but he is completely fluent in English so they have no problem communicating. I could tell that he loved her from the way he acted around her. It was definitely love," he said.
"It may be that he gets involved in restaurants and bars but he's never going to do a 9-5 job. He's too interested in having fun to want to work," he added.
