The pair, who have been married for 18 months, appear to have been living apart for some time and have not been pictured together since October.
Now the speculation about their marriage has been hit by a new report that their marriage is over for good.
According to The Sunday Mirror, Cheryl has begun formal legal proceedings by filing paperwork which cites irreconcilable differences.
The report also states that the couple split up five months ago, but are determined to stay good friends.
A source tells the newspaper that The X Factor judge "realised she had married too soon and had been swept away by a bit of a whirlwind romance.
"Over time it became clear to each of them that they were very different people and from very different worlds.
"They are now focusing on making sure they stay friends. The divorce is amicable and they have both said they will always be there for each other."
The pair met through mutual friends and married in secret on the island of Mustique in July 2014 after a whirlwind romance.
However, now restauranteur Jean-Bernard is said to have moved out of their marital home in London, and is spending most of his time in the US.
Just this weekend, he was pictured still wearing his wedding ring.
Neither Cheryl nor Jean-Bernard have officially commented on the reports at the time of writing, however Cheryl did take to Instagram on Saturday (9 January 2016) as the news broke.
She shared a new selfie with her two million followers, who were quick to show their love.
Jean-Bernard also turned to Instagram, posting a cryptic message to his fans.
He wrote: "Out Of The mouth of children comes The Truth... Get informed before you get opinionated..."
The 'Parachute' singer, 32, divorced her first husband Ashley Cole in 2010 after four years of marriage.
