Cheryl Fernandez-Versini 'set to divorce husband' after 19 months

X Factor judge Cheryl Fernandez-Versini is reportedly set to divorce her French husband after just 19 months of marriage.

The singer is filing divorce papers from restaurateur Jean-Bernard on the grounds of his "unreasonable behaviour", according to the Sun on Sunday.

The newspaper claimed the pop star was unhappy with her husband's jealousy over the amount of time she spent with other men and her dogs, Chihuahuas Buster and Coco.

A report in the Sunday Mirror claimed the couple secretly split five months ago.

The couple wed in August 2014 in a small ceremony on Mustique in the Caribbean after a whirlwind romance just three months after they met in Cannes.

It will be Cheryl's second divorce after she and footballer Ashley Cole split in 2010.
