The singer and X Factor judge is filing divorce papers to end her relationship with restaurateur Jean-Bernard Fernandez-Versini, The Sun On Sunday said.
The tabloid claimed the pop star was unhappy with her husband’s jealousy over the amount of time she spent with other men and her two dogs.
The pair married in a small ceremony on Mustique in the Caribbean in August 2014, just three months after they met in Cannes, France.
The Sun on Sunday quoted a source as saying: “Cheryl is divorcing JB on the grounds of his unreasonable behaviour. She has had enough of his jealousy.
The Sunday Mirror claimed the pair secretly split five months ago, and that she had realised they had married too soon.
The former Girls Aloud star hinted at her unhappiness on New Year’s Eve when she posted to Instagram a photograph of herself kissing her middle finger.
She wrote: “Bye 2015 ... you’ve been real!!!!! You have taught me a lot but I am happy to see the back of you!!”
