After gorgeous Chezza posted a picture to Instagram this week showing her at the X Factor auditions in London, one fan reportedly responded to say they didn't like how Cheryl looked.
Dissing Cheryl? That's not OK with the husband.
According to reports, the fiery Frenchman hit back with a few Instagram comments of his own, defending his beautiful missus.
JB's Instagram is private but it's claimed he wrote: "She is the most beautiful woman on the planet and she wants to share it. #sharingiscaring No seriously she is."
He then apparently added: "And I can tell you something else, she really cares about her fans and is touched by all your support. Now for the hater, please continue talking #wasteofenergy. I wish I had that much time hating and waste energy.
Lucky Cheryl. A knight in shining armour!
The Girls Aloud singer married JB in a secret beach ceremony on the Caribbean island of Mustique in July. It came as a shock to fans as the couple had only been dating a few months and hadn't even announced an engagement.
Now, they're in the UK while Cheryl films the auditions stage of this year's X Factor.
She'll make her return to the show for the first time since 2011 alongside Simon Cowell, Louis Walsh and Mel B. The 11th series of X Factor airs on ITV later this year.
